Hello.  This I am new to this group, so please forgive me if I'm
bringing this issue back from the dead.

I am running Windows 3.0 in 386 Enhanced mode on a 386/25 with 4megs of
RAM.  I'm transfering a file from a UNIX host to my using Zmodem
protocol with sz on the UNIX side, and WinQVT 4.45 on the PC side.  The
problem is that every 3 to 4 Kbytes of data, something wrong happens
(eg. WinQVT reports a bad CRC, bad packet or something).  Then it seems
take an eternity to recover from that error before it proceeds with
transfer.  Because of this, the transfer throughput has been pathetic
(on a small file -- ~12Kb, the overall transfer rate was 700bps on a
2400bps line.  On a large file -- ~300Kb, the overall transfer rate
dwindled down to 300bps on the same line).  Any idea on what's going on,
and how to remedy the situation would be greatly appreciated.
