I am having trouble downloading binary files using kermit so I thought that I would try and use the xmodem at school but every time I try to use it I always get no reply and eventuall my xmodem just times out and I get nothing received. I was wondering if anybody has ever used the xmode that comes with UNIX and what kind of xmodem is it, like xmodem or xmodem crc I haven't got either one to work. Mark Simmonds msimmond@ub.d.umn.edu

I've had a similar problem: Xmodem starts fine, but it hangs after the
19th block. Also, Xmodem-1k stops at 19 blocks, both checksum and CRC. This
is a real pain, especially because the only system I have access to that has
a working Xmodem server is at 1200 baud. Whoopee.
Is there a simple fix, or is it a problem with the actual Xmodem protocol
on the system?

Are you sending or receiving? I can only send to my UNIX account if I log on in a certain way (directly through a port selector; if I log onto a "terminal" account and transfer through there, it fails). In fact, sometimes the phone even hangs up... There are widespread problems with the last block not being sent... > Is there a simple fix, or is it a problem with the actual Xmodem protocol >on the system? What comm program are you using? I've found that an old version of Z-Link will succeed in certain places where ProTERM fails. > krb20699@uxa.cso.uiuc.edu -- fadden@cory.berkeley.edu (Andy McFadden) ...!ucbvax!cory!fadden labc-3dc@widow.berkeley.edu (expiring soon)

Note that block 19 of an Xmodem transfer has a block count in binary equal to Control-S. This is often interpreted by communications equipment as a xon/xoff control sequence. I know that I have to deal with a system in which this cannot be turned off - thus I have to use kermit to communicate with said system. -- Larry W.
