BEING A RELATIVELY NEW USER ON THE NET, I NEED SOME HELP. MY EQUIPMENT IS A TELEVIDEO 803 COMPUTER AND A HAYES SMARTMODEM 300. AFTER XSFERRING FILES FROM OTHER HOSTS, I.E. SIMTEL20, I HAVE REPEATEDLY TRIED TO DOWNLOAD THE FILES TO MY COMPUTER USING KERMIT 3.1, KERMIT 3.6, AND MODEM730. IN EACH CASE, I RECEIVE UP TO 50-80 PACKETS WITH NO OR VERY FEW RETRIES. AT THAT POINT, THE PROGRAMS "BOMB" OUT WITH THE MESSAGE "UNABLE TO RECEIVE DATA". IN THE CASE OF KERMIT 3.1, I ALSO GET A MESSAGE "BAD CHECK SUM". SINCE I CAN RECEIVE SMALL FILES (1-8K) WITH NO PROBLEMS, I AM PRETTY SURE THAT THE PORT ASSIGNMENTS ARE CORRECT. EVERYTIME I TRY TO COPY ANYTHING LARGER, THE SYSTEM FAILS. THE GUYS WHO HELPED ME MODIFY THE PROGRAMS FOR MY COMPUTER ARE STUMPED. I SURE COULD USE SOME HELP. RON OWENS -------

From: David Towson (CSD) <towson@Amsaa.ARPA> Ron - I'm going to take a stab at your problem. MDM7xx MUST have an 8-bit data path to work. This is because of the way the sector numbers are sent from transmitter to receiver, and has nothing to do with the type of data (ASCII text or binary) being sent. I do not know what Kermit needs, or whether you have an option of 7 or 8 bits with Kermit. Perhaps someone else will comment on that. My question, then, is, are you using an 8-bit transfer path? If not, I think that's your problem. Dave towson@amsaa

The Kermit protocol includes conventions for 8th bit quoting and control-char
quoting to permit transfer through restricted data channels. (However, not
all implementations implement all features).
