Hello, I have a question about PROCOMM PLUS and ZMODEM. I'm not very familiar with either, and as a result I am having problems understanding exactly how PROCOMM uses the ZMODEM protocol. We are developping an application that uses ZMODEM for one way file transfers and also some custom command (non DOS) sequences, that come from the sender of the files. ZMODEM of course allows you to send commands, but PROCOMM PLUS does not seem to let the user send any commands, just files. Am I missing something? Any thoughts/help would be greatly appreciated. Thank you in advance, Steve Hoskins Allen Bradley Corporation Motion Control Divisions Highland Heights, Ohio

- ZMODEM is a *file* transfer protocol. Commands are sent via normal
-terminal mode typing before ZMODEM itself is invoked.
And you must believe what you read in PC Magazine software reviews.
ZMODEM includes "Command Download" with optional security verification.

Speaking of Procomm Plus 2.0 and ZMODEM.... Procomm Plus is a nice little terminal emulation program. However, after using it for a few weeks now, it seems to have a brain-dead implementation of ZMODEM. Using a pair of T2500 modems in PEP mode, I only get about 700 to 800 cps when I'm lucky. Most of the time, the file transfer simply fails for large files (say over 50K). Telix, on the other hand, seems to have ZMODEM implemented correctly. File transfer occur at a good clip and I have yet to see it fail (unless the machine on the other end actually crashes :-). Speaking of crashes... I've also noticed that Procomm Plus 2.0 causes my QEMM-386 v5.12 on my DOS box to crash every now and then. -- Todd Ogasawara ::: Hawaii Medical Service Association Internet ::: todd@pinhead.pegasus.com Telephone ::: (808) 536-9162 ext. 7
