[comp.dcom.modems] XMODEM 1K documentation

tnixon%prodev.decnet@sf780 (PRODEV::TNIXON) (03/03/90)

- I am looking for a technical manual containing concise information
- on the file transfer protocol Xmodem 1K. I have the reference
- material Xmodem, CRC Xmodem, WXmodem File Transfer Protocols written
- by Peter Boswell but this does not contain any information on Xmodem
- 1K. If anyone can give me source of reference I would be most
- grateful. 

As far as I know, XMODEM 1K is identical to XMODEM CRC except that 
each frame contains 1024 bytes of data instead of 128 bytes.  Some 
programs implement an automatic startup mechanism that sends "CK" 
from the receiver instead of just "C", but I don't know just how 
widely accepted this is.

My source for authoritative information on these protocols is Chuck 
Forsberg of Omen Technology, ...!tektronix!reed!omen!caf, or through 
his Telegodzilla BBS at 503-621-3746.  There is a good file on the 
subject on Compuserve, but he may have it on his BBS as well.
