The rz/sz came with the system (NCR Tower 800 running SYS Vr3). TELIX is a general purpose tele-comm program. similar to (but much superior IMHO) Procomm. I have got transmittions to work over direct-link at 38400, with very few retries or NACks or any problems at all. I have got it to work with still as few problems using USRobotics modems at 9600. I did try DSZ once (a demo copy) and I didn't really like it so I stuck with TELIX. -- #include /* Rick Copley - rickc@telly.on.ca */ main() /* PROGRESS Programmer/Systems Analyst */ { typedef long lotsa; /* Time spent hackin isn't wasted */ lotsa *fun; /* unix - Live Free or DIE ! */ time_t in; fun = (lotsa)hack(in); /* following the hacker ethic */ }
