[comp.os.minix] problem with ZMODEM in zterm

ahalim@ics.uci.edu (Antony Halim) (05/20/91)

I have trouble using the ZMODEM protocol in zterm when trying to
tranfter file to/from a UNIX system. Everytime I've issued the
rz/sz command to the zterm, the zterm immediately says that the
transfer has been successfully done (actually not), and prompts
me to exit and run the zterm again. I did, but then the terminal
always hangs and no transfer of file has actually taken place.
Has anybody experienced this thing and know what seems to be the
problem?

Thank in advance.

Sometimes I get similar responses from my Unix system, and it has to do with a
sytek box hooked up to the LAN at school.  The modems are set up such that when
I call in, it goes through a sytek box, which uses the same ^s ^q flow control
that x,y, & zmodem use, so that downloading with these protocols is hopeless.
The only solution for us here is to use kermit.  There is a good kermit program
for the Mac called MacKermit .98  .  It can handle packets of 1016 characters,
so that it has a reasonable transfer speed.  
  If the kermit protocol is available on your unix box, I would recommend
trying it.
