Could someone please send me the file 'xmodem.h' that is part of the Pcomm program? I either lost the file or didn't receive it with the rest of the Pcomm software. Thanks in advance for your help. I'm also very interested in installing a 3.5" floppy drive on my UNIX-PC. Anyone care to post the "what equiptment and how" list? Tom Czarnecki att!mtfmi!tjc
