For anyone that is interested,
(many thanks to Jacob Parnas), Jacob and I
got the Microcoms transferring files correctly.
There was a number of things that we did:
- We SET XON/XOFF off ( this screws up Zmodem )
- We log on at N,8,1 ( E,7,1 screws up Zmodem )
- We got the latest copy of sz and rz from uunet. ( the old rz was screwed up )
Here are some observations:
- Logging on at 38400, we get up 2500 CPS when transferring large files.
Here are some questions:
- We tried adding Hardware Serial Flow (AT\Q3) bidirectional Hardware serial
flow. We thought this would speed up the transfer since Zmodem
transfers with serial flow control OFF, causes Zmodem to
do a lot of error correcting when the buffers overflow.
Well, to make a long story short, (AT\Q3) bidirectional Hardware serial
flow causes Zmodem file transfers to fail.
Does anyone have any ideas why
"(AT\Q3) bidirectional Hardware serial
flow causes Zmodem file transfers to fail." ?
- Does anyone know of an OS/2 communications program
that supports 38400 baud?

Obviously, if you disable XON/XOFF *and* hardware flow control, then your COMM software had better be GREAT to handle 2500cps!! > Well, to make a long story short, (AT\Q3) bidirectional Hardware serial > flow causes Zmodem file transfers to fail. No, I ALWAYS have AT\Q3, and never have a problem. Maybe your TTY driver is sick? >- Does anyone know of an OS/2 communications program > that supports 38400 baud? OS/2, TOPVIEW for the '90s! Try ZCOMM/PRO-YAM under DOS. RGDS GARY

Ideas, yes. Answers, no. It could be that your hardware - or the device drivers - simply don't support it, or that their configuratrion would require substantial revision (when I plugged a TrailBlazer Plus into an AT&T 3B4000 on a lark a few weeks back, I had to make a few "adjustments" to the TB's config to make up for what the 3B4000 WASN'T doing with the port...) > - Does anyone know of an OS/2 communications program > that supports 38400 baud? Colin Sampaleanu (author of Telix) was told not to expect anything over 4800 bps to work reliably under OS/2. I suspect that this was a worst case scenario, probably assuming a 286 and that a compatability box would be running at the same time and introducing the old 286 mode-switching fun... -- Geoffrey Welsh - via FidoNet node 1:221/171 UUCP: {{uunet!}watmath!xenitec!}zswamp!171.0!Geoffrey.Welsh ARPA: Geoffrey.Welsh@p0.f171.n221.z1.fidonet.org
