Well, I didn't really pay too much attention to the articles that flew by concerning hooking up a Trailblazer to tty000 on the Unix-PC. You see, I figured that I'd probably invest in a laser printer before I shelled out the bucks for a trailblazer. I now find myself in the happy situation of wishing I'd saved some of that info. My benevolent employer has provided me with a 'blazer to fiddle with since I have a home unix system. So, would one of you who has already done it give me some pointers? What do I need to do to get uucp to use the Trailblazer? I've managed to get it working with the ATE stuff (yuck! I also want to figure out how to get it working with the mdm program - hi, Emmet!)

Hi, Here is what works for me to control a Trailblazer on my 3b1. I have ver 4.0 firmware now, but the vax I talk to is still using some level 3.x firmware, so I do not get the benefits of data compression, etc that level 4.0 gets you. None the less, I typically get uucp throughputs of 850-950 char/sec on "short" files under 40 Kbytes. With longer files, I get "only" about 550 char/sec. Note, you may want to add a couple of new entries to the attached modemcap file to have an entry that initializes ATs95=0 for 1200 baud connections to computers endowed with non MNP modems (3b1's On Board Modem, for example). Unfortunately, it is the nature of MNP to go brain dead when calling a plain-jane modem without MNP. This is not a bug in the Trailblazer, but rather a bug in MNP. I have seen the same thing happen with MNP on a US Robotics and on a MIcrocom 9624. I have included a couple of DIR entries in the attached L-devices file so that you can use "cu -ltty000 -snnnn" to directly program the Trailblazers S regiesters for those special occasions. Since L-devices is scanned top-down for an available device by uucico and cu, you should probably stick with the ordering in my example. Note to get 300 baud out of the On Board Modem, it seems to need a different name than OBM for that rate- I kind of liked "SOB" for Slow OBm. I didn't want to insult the Trailblazer by making it have a 300 baud modemcap. One thing I haven't implemented in modemcap is to search for return strings like "BUSY" or "NO DIALTONE", and return with an error from dialing. That, as they say, is left as an exercise for the reader. --Bill ----------------------cut for modemcap-------------------------- #sccs "@(#)uucp:modemcap 1.3" # Modemcap file # Add the following lines to the bottom of your current modemcap # # Telebit trailblazer modem # same as hayes, but send a couple of "A"s first to get autobaud right # Name=telebit9600 t9|telebit96|telebit 9600:tr=\r:wp=\r:wk=K:wt=T:\ :ta=AT\r:ph=ATDT:\ :eh=\r:\ :d1#1:d5#5:ti=A:wi=A:\ :d2#30:\ :pl=tid1tid1tiwid1tad1wpwpwkwpphd2wpwpwttr: # # Name=telebit2400 t2|telebit24|telebit 2400:tr=\r:wp=\r:wk=K:wt=T:\ :ta=AT\r:ph=ATDT:\ :tp=ATS50=3\r:\ :eh=\r:\ :d1#1:d5#5:ti=A:wi=A:\ :d2#15:\ :pl=tid1tid1tid1tiwid1tad1wpwpwkwptpwkphd2wpwpwttr: # # Name=telebit1200 t1|telebit12|telebit 1200:tr=\r:wp=\r:wk=K:wt=T:\ :ta=AT\r:ph=ATDT:\ :tp=ATS50=2\r:\ :eh=\r:\ :d1#1:d5#5:ti=A:wi=A:\ :d2#5:\ :pl=tid1tid1tiwid1tad1wpwpwkwptpwkphd2wpwpwttr: ---------------------L-devices-------------------------------- # "@(#)L-devices 5.0" # /usr/lib/uucp/L-devices # This file is manipulated by the ADMIN-KIT commands used to # configure outgoing data ports.

Thanks to all who have provided help, I configured uucp on my 3B1 to talk to the Trailblazer. Now, if I could just find someone in the San Jose area to feed unix-pc to me over a Trailblazer link... One small problem I have, though. If I configure tty000 to be a modem port, do I have to tell the Trailblazer to never say anything? It looks like tty000 and the 'Blazer get into a shouting match, and the 3b1 gets real s....l....o....w. My solution to this was to configure tty000 as an "other" and caller-only. Yes, I know, *real* 3b1 owners don't use the ua to do this sort of thing, but I am not experienced in unix system administration.... I don't have any dial-in users right now, but might someday. What will I need to do, tell the 'Blazer to be completely silent, or something? John Wilkes -- -- @work: -- {decwrl,ames,pyramid,prls}!mips!wilkes -- OR, for those of great faith: -- wilkes@mips.com

Reference 'mdm'... Hang in there, I've got a replacement for the 'mdm' program almost ready for release. It will allow external modems of different brands to be used for outgoing calls. Emmet P.
