[comp.sys.atari.st] xmodem

THANSEN@cosmo.UUCP (Thorsten Hansen) (08/24/88)

Is  there  someone who can help me with a routine for  the  XModem 
transfer protocol? Perhaps someone has an example program for it.

I would be thankful for any sort of help.
In this case, send me a short message please.

Has anyone had any success downloading using the BSD version of xmodem (v3.6)
using the ymodem batch protocol?  I am using Simon Poole's Uniterm (v2.0e) on
an Atari 1040ST, and it *ALWAYS* craps out on the second file in either 128
or 1K packet size.

Here is copy of my xmodem.log:

I have the following set-up in the Uniterm File Transfer Dialog Box:

	Timeout after:		10 sec
	Max # of errors:	10
	Accept Ascii NULL:	YES
	Packet size:		1024
	Error check:		CRC

Any clues?

I haven't had any problems down/uploading with Chuck Forsbergs programs
on the Unix side (rb/sb). Note that UniTerm only automagically disables
XOn/XOff flow control when called from the keyboard, not when called
from a macro (this might be considerd a bug). Anyway what error message
does UniTerm display?
