Xmodem 3.9 - Is it broke?

[Carl W. Bergerson]

Last week Xmodem 3.9 by Steve Grandi was posted to comp.sources.unix.

I compiled this version, without warnings or errors, under
RISC/os 4.51 using the bsd 4.3 compiler. I started testing it using
Procomm Plus 1.2 on a '386 clone under MSDOS 3.3.

I cannot get this program to function properly. Can anyone Help?

Details -

When doing a xmodem send text (xmodem -st <file>), xmodem appends
an arbitrary number of control Zs to the end of the file. See the
output of wc below for three files before and after downloading.

RISC/os Before download

   21     151     870
  297    1196    8438
  102     586    3839


MSDOS  After download

   21     151     870        0
  297    1197    8535       56
  102     587    3866       26

The fourth column in the MSDOS listing is the number of ^Z at the end of
the file. I also tried a Ymodem download and it added the same number
of ^Z.

When trying to do an xmodem receive (xmodem -rt) Xmodem never
synchronizes with PCPlus. See the xmodem.log sample below.

I have also tried uploading with Ymodem and several other variations
and they all have the same problem.


Any help or suggestions would be greatly appreciated.
