  Hi,

  I keep having zmodem problems with the new rs232 driver. The problem occurs if
I am receiving a file from a remote machine. After receiving 1K correctly, the
second and successing blocks have to be received at least twice. When zmodem
switches to very small blocks the problems still occur - this never happened to
me before, no matter how bad the line was. It happens with ANY file, ALWAYS
after succesfully receiving the first block.

  The fact that the first block is received correctly and the varied error
messages of zmodem seem to suggest a buffering problem (note that when receiving
from this particular remote machine, data is only received and nothing is send
back except in the case of an error). The problems occur with any modem speed,
however.

  Sometimes things seem to be allright again - for about 1K, then there follows
another wave of errors.

  Does anybody else have the same problems? Does anybody know how to solve them?


  Regards, Felix Croes
