Omen Technology owns zmodem. To get the specs and reference code will cost a few $$.
Early version of the sz and rz programs were released as free software, but I've never heard of a windows port of them. If you want to code something up in C, they might be a good starting point. http://www.ohse.de/uwe/software/lrzsz.html is decended from the old free rz/sz. Here's some other stuff: http://web.mit.edu/afs/athena.mit.edu/astaff/project/telnet/src/omen/ -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 19, 2005 1:19 PM To: Ken Cornetet; [email protected] Subject: RE: Modem File Transfer help Ken Cornetet wrote: > > Win32::SerialPort > > http://members.aol.com/Bbirthisel/alpha.html > > This will let you send and receive bytes via serial ports, but AFAIK, > there isn't any perl code for doing zmodem transfers (but then I > haven't done a great deal of looking, either). that will let me do basic communication and such, but wont allow file transfers (at least not ZModem). > Best I remember, zmodem is not a trivial protocol to implement.

Either > of these would be fairly easy to implement in perl. unfortunately not. this particular product only has ZModem. which kind of sucks, because I can't seem to get TeraTerm to work correctly, either, and so am forced to use HyperTerm as an interface. It looks like I'll have to try and do this in C or VB. which is a drag, because my test suites so far have been entirely in Perl. > > Robert Johnson wrote: > > > > > > i have some devices that send data files via ZModem. i want to > > automate the process of receiving these files for parsing via a perl > > script. > > > > after searching CPAN and other sites, i find that it's not as easy > > as i would have thought. > > > > Devices::Modem doesnt allow file transfer, and is apparently very > > limited in the things that it can do. mgetty/vgetty is only for *nix > > machines. these are the only things i can find related to modems. > > > > is getting a modem connection via perl that difficult? > > > > any help will be great, thanks > > > > robert > > _______________________________________________ Perl-Win32-Users mailing list [email protected] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
