[mod.computers.vax] XMODEM and XFER gasping...

macmillan%wnre.aecl.cdn%ubc.CSNET@RELAY.CS.NET (John MacMillan) (12/01/86)

WE have two versions of XMODEM. XFER, written in C, came from the University
of Regina; the other was written in Fortran and I don't know where it came 
from. Both quit at the same point. 


I tried XFER on the vax, sending to SYMPHONY on an IBM PC and it also
hangs up after sending 2432 bytes (19 blocks). Short files transfer ok.
XFER seems much faster than XMODEM.

	Any help you can give would be appreciated.

Has anyone experienced this problem before? 
  Does anyone have a version of XMODEM on the VAX that does not show
this problem? (if so, would you please send a copy?)

Thanks..

        I would suspect your XMODEM programs don't internally disable
TTSYNC or HOSTSYNC: Block 19 starts with the character 19 which is a
ctrl-S. The solution is to SET TERM/NOTTSYNC/NOHOSTSYNC/NOREADSYNC.
I wrote (yet another) XMODEM program that does all this internally.
If you're interested, post a message.
