This message is intended for Bill Currie the
author of BCSio20. If you could please forward
this message, I would appreciate it.
Hi Bill,
I hope you're still supporting BCSio20. I'm
stuck and was wondering if you could take a look
at this code and let me know what I'm doing
wrong.
Attached is my source and the logfile that it
writes. You will be able to tell what the
input file is by reading the logfile.
Basically, I have a label writer/psuedo printer
that speaks a proprietary language called pywrite.
I'm looking to have my C code read a set of
pywrite commands and send them to the printer
via COM1 on Windows 95.
The code seems to execute without errors, but
I'm not seeing the labels come out of the printer.
When the printer reads a "showpage", a new label
should emerge.
I am using your included linker, and have even
disabled COM1 under Win95 per your suggestion and
still can't seem to get it to print.
Note that in my source, I first tried using the
sio_write function, but I kept getting a SIGSEGV,
so I switched to sio_put which doesn't choke, but
also doesn't work.
FYI, I won't have access to my email for a week,
so if you ask for more info, I'll get back to you
as soon as I am able.
TIA,
Eric
