Can someone tell me where to find a description of XMODEM and YMODEM, hopefully including most of the common variants (1K,4K, supercharged)? -- Doug Reeder USENET: ...!tektronix!reed!reeder from ARPA: tektronix!reed!reeder@berkeley.EDU BITNET: reeder@reed.BITNET the Little Mermaid on materialism: I just don't see how a world that makes such wonderful things ... could be bad!

Could anyone with any pointers to such information send them my way too? Thanks, Matt.

I have had absolutely 0 luck on getting anything on where to get hold of algorithms for X&Y modem protocols. I did get abt 150 pages of C source code for ZMODEM (all printed out and gone, sorry). It seems that no one wants to tell anyone else how to program these protocols... ------- ======================================================================= "All right, I want a nice clean fight. | Andy....

Andy, the protocol documentation for X/Y/Zmodem is available from SIMTEL20, along with many other protocol documents. You can get them with anonymous FTP or via LISTSERV@VM1.NODAK.EDU (also known as NDSUVM1.BITNET).
