I installed our first Trailblazer Plus late last month, and have been
so far unable to get the throughput up to where it should be....here's a
sample of the status-quo..

van-bc!paster M (2/5-12:34:58) (C,829,1) [tty1A] -> 785 / 1.150 secs, 682 bytes/sec
van-bc!news M (2/5-12:35:25) (C,829,7) [tty1A] <- 6769 / 15.750 secs, 429 bytes/sec
van-bc!news M (2/5-12:36:26) (C,829,9) [tty1A] <- 71897 / 142.800 secs, 503 bytes/sec
van-bc!news M (2/5-12:36:43) (C,829,13) [tty1A] <- 6122 / 14.500 secs, 422 bytes/sec
van-bc!news M (2/5-12:43:03) (C,829,49) [tty1A] <- 29262 / 57.950 secs, 504 bytes/sec

The system is a 386, running at 25MHz under SCO Xenix 2.3.1. The Systems
file for van-bc is set for 19200 (tried 38400, but it wouldn't fly), and icgnu
is set for 9600. The same Devices listing is used for both.

I am using a standard 8250-type UART, with no buffers (a'la 16550's)....
would appreciate any suggestions which would assist me in tweaking the system
and getting it up to speed....400-600 baud isn't acceptable, and I know that
the system is capable of more.....where should I begin?
