Telebit and Xenix

[Laverne E. Olney]

This message concerns SCO Unix/Xenix and Telebit Trailblazer-Plus
modems.  I would like as many people as possible who use these
products to mail me THEIR configurations and I will post a summary.
  I did have a stable configuration with Xenix 2.3.2 (downloading
news at 900-1100 bytes/sec) but using the identical settings on
Unix 3.2 gives transfer rates of only 460-550 bytes/sec (9600 baud).

Modem set-up string to answer (host):

Using the setup described, what is the usual range of data transfer speeds?

Do you use "dialTBIT -z /dev/tty1A 19200" to set up your modem?

Which communications program do you use to call out (e.g. cu, YAM, procomm)?
