Hello, Could someone please send me (or let me know where to find) a brief description of the various versions of the Modem protocol-- Umodem, Xmodem, Modem7, Ymodem, etc. I'm NOT looking for actual descriptions of the technical details, just a comparison of the differences and features, and which of them (if any) are compatible with any others. Thanks! Steve Dennett dennett@sri-nic.arpa -------

The following file, available from SIMTEL20, will probably answer your questions about the various programs that use the Christensen MODEM file transfer protocol (sometimes erroniously called XMODEM or MODEM7 protocol). Filename Type Bytes CRC Directory PD:<CPM.MODEM7> YMODEM.DOC.1 ASCII 49446 6076H If you have any more questions, address them to: Info-Modem7@SIMTEL20.ARPA which is a mailing list that specializes in MODEM7, MEX, YMODEM, UMODEM, etc. (administrative requests to Info-Modem7-Request please). --Keith

On the other hand, I'm looking for a technical description of XMODEM, MODEM7 (batch XMODEM), YMODEM, etc... I'm trying to add a batch mode to my terminal program but have had no luck whatsoever deciphering Tom Jenning's TELINK document. Apparently he assumes you already know how to do batch XMODEM. -- -- Peter da Silva -- UUCP: ...!shell!{baylor,graffiti}!peter; MCI: PDASILVA; CIS: 70216,1076
