I am using DSZ.COM on a 386-AT to upload and download files from a VAX/VMS
system that has RZ and SZ.  The transfers are done over a direct serial link
(i.e. no modem, just cable.)

Previously I have been able to do both uploads and downloads at 9600 baud with
no problems.  A recent line upgrade now allows me to run my PC (as a terminal)
with Kermit at 19200 baud.

The problem is that while SZ(VAX) -> DSZ(PC) still works fine at 19200 baud,
DSZ(PC) -> RZ(VAX) now gets all kinds of errors at 19200 baud.
I have set the speed correctly for DSZ in each case.

The errors start with the first 1024 bytes of data transmitted, and DSZ says
Got ZRPOS.

Okay, I looked in DSZ.DOC, and ZCOMMDOC for a solution.  They indicated that
it was probably a flow control problem.  So I tried DSZ receive with
handshake on, off, slow, both, and none of them worked - I still got the
same errors.  Now it must be that the VAX cannot respond quickly enough to
the PC at 19200 baud.  I have tried a couple of different versions of the
software on both the VAX and the PC and get the same errors every time.

Can anyone offer some advice? (apart from going back to 9600 baud....)

Cheers,
Liam.
