I am writing a testing application for checking out a TCP to Serialbridge component. I am using Lazarus 1.8.0 and fpc 3.0.4 on Windows 7 For the serial port handling I found the "built-in" Serial unitdescribed here:http://wiki.freepascal.org/Hardware_Access#FPC_built_in_Serial_unit Now I have a few questions about its usage: 1) Serial port name-------------------When opening the port the example does this: str(ComPortNr,tmpstr);ComPortName:= 'COM'+tmpstr+':';serialhandle := SerOpen(ComPortName); So for say port 29 this results in ComPortName 'COM29:'Is this always the case? I have a hunch that for port numbers 1..9 theWindows port naming is different than for higher port numbers... And if I want to port this to Linux, I guess thta the name iscompletely different, but no hint is given.
I did quite lot of work on the serial.pp unit more recently than that wiki page, in fact I didn't even know it existed. Please refer to the comments in that file in the first instance.
