[fpc-pascal] serial.pp - I can't talk to modem
Hi,
I've created a simple console application for Linux and Windows. It's
a port of older Win32 API code I wrote years ago. All I'm trying to
do is dial a phone number and then later hang-up the phone.
I've got a external USRobotics Courier V.Everything V.90 X2 connected
to COM1 (/dev/ttyS0). The modem works perfectly in 'minicom' (a modem
terminal application). But for some reason I can't get anything out
of the modem using the serial.pp unit. I can see the RD and SD lights
flicker briefly on the modem, but nothing else.
I even tried to simply take the modem off the hook (ATH1 command) and
even that doesn't work, but again in minicom it works fine.
Can anybody please look at the following code and tell me what I am
doing wrong. Thanks in advance.
I'm using FPC 2.2.0 under Linux (Ubuntu 7.10) and Windows 2000. I
made sure my user under Linux has access to the /dev/ttyS0 device. I
even tried to run it as root. No difference.

Shouldn't you set at least RtsCtsFlowControl ?
As far as I know, you must at least set some options, such as the baud rate
and so on, sersetparams seems to do most of the needed actions ?

Even if I uncomment the 'SerSetParams(...)' line shown above, it makes
no difference. :-(
I'm busy reading through the article mentioned below to try and see
what I'm doing wrong. So far I found no hints as to the cause of the
problem. The article does mention a CR (#13) must be sent as the last
character in each command. I appended #13 to my dial string, but still
nothing.

Yes, but it should be
SerSetParams(serialhandle, 2400, 8, NoneParity, 1, [RtsCtsFlowControl]);
No ?
Also, 2400 baud seems very slow ?

What are the permissions on /dev/ttyS0 ? Have you tried running it

I have no idea! :-)
OK, I changed the code to the following... I it should do, is take
the modem off the hook... nothing happens. :-(
-
serialhandle := SerOpen('/dev/ttyS0'); // COM1 under Linux
if serialhandle = -1 then
writeln('Failed to open port');
SerSetParams(serialhandle, 2400, 8, NoneParity, 1, [RtsCtsFlowControl]);
s := 'ATH1' + #13;
SerWrite(serialhandle, s, Length(s));
-
> Also, 2400 baud seems very slow ?
That should not be a issue. All that the code is supposed to do is
dial the phone, nothing else (hence the reason I didn't even bother
with the SerSetParams call in the beginning). The end result should
allow the user to click a button next to a phone number and the modem
dials the number for the user. No other communication happens.
Anyway, I tried 19200 speed as well, but as expected, no change. This
has been driving me insane for a few days now. Grey hairs popping up
all over the place! :-)

[fpc-pascal] Maybe a new fpc book :)
I recently responded to a question on the community board asking about an fpc book by recommending a Turbo Pascal book by Jeff Duntemann. His book started me out as a Pascal programmer in 1989 and I still find these old books useful from time to time. I have two by him: Turbo Pascal from Square One The Complete Borland Pascal Mr. Duntemann has also written other programming books and was employed by Borland for a while as a technical writer. I have found his books to be the best available for learning Pascal. When I responded to the board question it started a train of thought that resulted me in contacting Mr. Duntemann about writing a book on FPC. To my (pleased) surprise I found him provisionally enthusiastic for the project.(He hasn't made his mind up yet). He has the following questions for the community. POSTED WITH HIS PERMISSION. 1. What OS is most-used for Free Pascal? Windows? Linux? 2. What libraries do most people use for console (i.e., "terminal" or text-mode) apps? I dislike ncurses; is there a better way? 3. Does anybody really use Free Pascal to write Win32 apps? 4. Do people make heavy use of Free Pascal objects? These are important questions, because I want to bring newcomers up to speed with the tools and OSes they're most likely to use as they get better. I will probably release the rewritten book as a free ebook, and offer printed copies of the book through Lulu.com, where I publish a number of other things now. See: http://www.lulu.com/copperwood I don't expect to make much money on the project; I made my money on the book back in 1993 when it was first run.

Re: [fpc-pascal] Maybe a new fpc book :)
He has the following questions for the community. Since I feel as being part of the community, I'd like to answer. :) 1. What OS is most-used for Free Pascal? Windows? Linux? For me... 80% Linux, 20% Windows, 0% MacOS. But this will change if I got a MacBook, perhaps I'll have 20% usage on this OS. :-D 2. What libraries do most people use for console (i.e., "terminal" or text-mode) apps? I dislike ncurses; is there a better way? For console app, I used basic CRT unit provided by FPC. 3. Does anybody really use Free Pascal to write Win32 apps? I do. I never wrote console app on win32 using fpc, but I wrote some GUI apps on win32 using Lazarus which is powered by fpc. ;) 4. Do people make heavy use of Free Pascal objects? Does 'objects' here refer to object oriented programming or refer to TP's style class? If it means OOP, then I do make heavy use of OOP in FPC, especially the FCL. It it means the last, then I no longer touch this object paradigm since I used Delphi. ;) These are important questions, because I want to bring newcomers up to speed with the tools and OSes they're most likely to use as they get better.

I want to note that mostly all Windows users download FreePascal and Lazarus by their own from the original download servers. OTOH many Linux users get FreePascal via their distribution.

I agree...plus the Linux downloads are split into lots of small packages, were the Windows download is one file. This is also what drives me mad about companies publishing the populaty of OSes based on sales or whatever else (I mention no names.. :) ). Linux has a huge "invisible" community because we are allowed to distribute copies legally and get them from all over the internet without payment. Windows OS copies are much easier to track because they have to be bought and registered. I'm going a bit off-topic here, sorry. But again, Linux users can now get copies via 'apt'. Then what about the loads of people using 'svn' to keep up to date. I think I've only downloaded one copy of FPC for Windows and Linux, but have been keeping up to date via svn for the last 3 years.

Grrr - the punitive measures in the anti-trust case didn't go far enough! I don't buy software unless I have no choice. e.g. I have written my own programs for budgetting, stats, etc.). Eventually I want to make some of my programs multi-platform, but it would still be command-line based rather than windows based (graphics just slows everything up, so unless needed... "a picture is worth a thousand words, but it takes 10,000 times the memory"). 2. What libraries do most people use for console (i.e., "terminal" or text-mode) apps? I dislike ncurses; is there a better way? CRT and strings, and that's about it. 3. Does anybody really use Free Pascal to write Win32 apps? Not specifically, but I try to make my DOS programs work in Windows as well (not easy, given how much MS crippled their version of DOS - at least one program I gave up on keeping it Windows compatible, though in future I might make use of some multi-platform system units to help this project. Have to face facts that most people use Windows, even if it's a really crappy OS :-\ ). 4. Do people make heavy use of Free Pascal objects? Nope, but if it was covered in a book I might be more inclined to do so. It would be good to have a more up-to-date Pascal book (there are features in FPC which aren't in my old Pascal books. e.g. OO, strings, passing filenames as parameters, etc.) - I'd buy a printed copy (or an E-copy I could print). thanks, DONALD.

I agree...plus the Linux downloads are split into lots of small
packages, were the Windows download is one file.
I have the impression the amount of Windows users is still significantly
bigger than the amount of Linux users. However, Linux users are more
active in the community.
A good book targets both groups of users and teaches users to use
{$ifdef windows}/{$ifdef unix} where needed.

You can use crt or the video unit provided by FPC. You have Free Vision, the Free Pascal port of the old turbo vision. Perhaps it is usefull to node him the use cases in which you would choose what API: * Simple text mode programming: crt * Advanced textmode UIs: Free Vision * Maximum flexibility: Video & keyboard units Ncurses could be used as "the unix way", but is rather primitive compared to FV. 3. Does anybody really use Free Pascal to write Win32 apps? Sure. Some people use it to create their flagship applications. Indeed, but there are three categories of Win32 programs that are popular: * LCL applications, coded through Lazarus * Games, often using JEDI-SDL and OpenGL * Win32 command line applications Users from each group might be interrested to learn different things... Users that don't belong to these groups do of course also exist. Daniël___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] Re: Maybe a new fpc book :)
Hello, 4. Do people make heavy use of Free Pascal objects? I will answer this question in the sence of meaning the object as a type for OOP. Recently in my two pascal projects, which by the way are relatively very current, I used only "objects" and not "classes". You can find those projects here: http://www.aggpas.org (Vector Graphics Engine, native port) http://www.icu4pas.org (Unicode I18N library, direct class wrapper) Every delphi programmer would wonder why the hell to use that archaic type, which is marked as "obsolete" in Borland documentation. But it has a very strong technical background argument in simple fact, and that is impossibility to allocate classes on the stack, because classes are always allocated on the Heap. Here again delphi programmer would very very wonder, why one would want to allocate classes on the Stack ? Answer is that those two project are direct 1:1 ports from C/C++, where classes technically can be on Stack and also on the Heap, and to mimic this behaviour is possible only when using "object" types and not "classes". That's my two cents Milano ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] Maybe a new fpc book :)
i'm a delphi programmer and a FP beginner, it completly lacks good books focusing on FP and LCL, the book i'm looking for: > 1. What OS is most-used for Free Pascal? Windows? Linux? mostly windows, but linux and osx are important too, crossplatform tricks are welcome. consider FP being cross platform is a main advantage over delphi and .net > > 2. What libraries do most people use for console (i.e., > "terminal" or text-mode) apps? writeln is enough for simple personal tools, but in 2008 is hard to sell a text-mode app, so this is not the killer library nowadays while internet and database lib are more important for modern real projects > 3. Does anybody really use Free Pascal to write Win32 > apps? absolutely yes, the vision behind lazarus is to replace Delphi > 4. Do people make heavy use of Free Pascal objects? absolutely yes, patterns and algorithms are interesting too. a question about the odience: should this book be for totally beginners or for (somehow) experienced programmers coming from others environments? ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
