I have recently seen an addendum by John Byrns to Ward Christensen's 1982 MODEM protocol document that discusses the CRC option (both were recently posted to net.sources). Has anyone written down "official" protocols for the batch file transfer mode of MODEM?? Comparing several different programs, I find that they differ in whether or not the file-name checksum is to be ACKed or not. I think these two cases are mutually exclusive! Thus, I would like to know the "official" way of doing things. -- Steve Grandi, National Optical Astronomy Observatories, Tucson, AZ, 602-325-9228 {arizona,decvax,hao,ihnp4,seismo}!noao!grandi noao!grandi@lbl-csam.ARPA

The MODEM7 "batch protocol" was never widely accepted because it is so very specific to CP/M. My understanding is that Ward is writing an article for Byte which describes the "YMODEM" protocol extensions as used by the YAM series of programs. A file describing the extensions is available on Telegodzilla (503-621-3746) as YAMPROT.DQC. -- Chuck Forsberg WA7KGX ..!tektronix!reed!omen!caf Omen Technology Inc 17505-V NW Sauvie IS RD Portland OR 97231 Voice: 503-621-3406 Modem: 503-621-3746
