I've been trying for some time now to get Zmodem working under Linux, and
am running into some really strange problems. I've tried posting this to
comp.dcom.modems (which seemed the logical place to start), but no dice.
I've been trying to use Zmodem from under the following comm programs:
*) minicom (which just core dumps and dies under 0.99 PL6)
*) xcomm (2 or 3 different versions)
*) pcomm
*) cu
*) ucu (which I just got today)
(btw, I don't have X, so I can't use seyon, which everyone seems to swear by.)
in each case, I've been trying to download a file from some remote BBS
system. I issue the commands on that end to start a Zmodem download, and
then use whatever the escape char happens to be for the comm program I'm
running, and ask it to run rz (using the appropriate command to redirect
stdio and stdout).
anyways, the result is simple: nothing. rz never seems to talk to the
remote end. it does appear to be dumping data onto the serial port, and
data does appear to be coming from the remote end, but they never seem
to see each other, and they each keep trying to initialize the other
end..... I've also tried forcing the matter, by calling rz as
``rz < /dev/ttyS0 > /dev/ttyS0'' with no difference whatsoever.
I've never run into this problem before (but then, I've always been the one
dialing INTO the UNIX machine, instead of dialing FROM it), so I'm assuming
there's something unique to using these programs under Linux.
I assume that someone has gotten this to work right....anyone know what's
going wrong? oh, btw, I've tried multiple versions of rz, too, and again,
no difference. I've read all the docs, and am doing things exactly as
they say I should be (which is also the way that makes the most sense),
but nothing works.
if nothing else, does anyone have a good non-X11 comm program that has
Zmodem built in, where I don't have to worry about broken comm programs
and/or broken versions of Zmodem?
thanks.....
