I'm trying to get a trailblazer T25AA modem to run HDB UUCP at high speed on my Xenix 386 system, release 2.3.1. I'm using dialTBIT as the dialer program and I can only get about 6100 baud max throughput. Rough timings of cu "catting" a file yield about 11000 baud throughput. Could someone send me the TB register settings/dialer scripts/etc. that are needed to get the TB to run at a higher throughput? Much thanks, -- Jim Stratton stratton%hpcupt1@hplabs.hp.com

If you're talking about a T2500 (or other PEP capable modem) I can assure you that when you initialize the modem with "dialTBIT -z /dev/ttyxx 19200" that the modem is properly configured. What you may be forgetting to do is enable the UUCP mode. To do this, add "Uu" to the phone number in your Systems file entry. Example: systemname Any ACU 19200 5551212Uu etc... The dialer will parse the phone number to enable options in the modem. You will find there are many modes that can be enabled. The dialer will return an error if you try to enable incompatible options. If your modem is a T2500, a friend and I modified the dialer for V32 support and fixed some other problems with the T2500. I'm consistantly getting better than 1400cps on a variety of machines with PEP modems. -- Scott crash!scotto

I am running SCO 2.3.2 and 9 times out of 10 get 1400+ cps on transfers using dialTBIT. I'll email my nram configuration.

And make sure that both modems DON'T have s111 set to 255. This is a common
mistake. The way all the local nodes around here have done is set s111=255
in nvram, and then place the calls AFTER resetting s111=30. You can NOT
change this after the connection.
