Setting up a Trailblazer on Microport 286

[John Gayman]

   Before I gave my first impressions of the Telebit Trailblazer running
under Microport Sys V/AT.  I have put together a list of exactly how I
have everything set up. It may save someone a few steps anyway. I've been
running the modem for several days and have been extremely impressed with
the response. I am still running all my News feeds late at night so the
interrupt problems at 9600 baud have not been a concern at all. I do plan
to implement an intelligent serial card sometime soon which should enable
9600 baud UUCP to run while other serial services are running. I am 
currently running 2.3U with Microports HonneyDanBer UUCP. Because of the
fact that Microports HDB doesn't appear to support the "Dialers" file, the
configuration has to be "modified" slightly as you will note below.


  These are the register settings I currently have set in the modem. 
Version 4.0 of the firmware appears to be the latest being supplied
by Telebit:

  The following are some entries from my /usr/lib/uucp/Systems. These
examples cover a couple different types of connects. Systems n3dmc & uunet
are at 9600 and use the modem in PEP mode. ka3adu is a normal 2400 baud
line with a Hayes at the other end. The reason for the extra stuff is that
because Microport doesn't support the "dialers", we must configure the
modem in the Systems file. In the area of login/password, I've found that
putting delays in between each character seems to increase the reliability
of the login being interpreted correctly.


n3dmc	SaSu,Wk0200-0600	Direct	9600	tty0	"" BREAK "" A\dA\dA\dT OK ATS50=255DT13335551212 CONNECT\sFAST--CONNECT\sFAST "" ogin:-BREAK-ogin:-BREAK-ogin:-BREAK-ogin:-BREAK-ogin: mylogin ssword: mypassword 
uunet	SaSu,Wk0100-0630	Direct	9600	tty0	"" BREAK "" A\dA\dA\dT OK ATS50=255DT13335551212 CONNECT\sFAST--CONNECT\SFAST "" ogin:--ogin: x\dx\dx\dx\dx\dx\r ssword: x\dx\dx\dx\dx\dx\dx\dx\r
ka3adu	Any	Direct	2400	tty0	"" BREAK "" A\dA\dA\dT OK ATS50=3DT5551212 CONNECT\s2400 "" ogin: mylogin ssword: mypassword 


   This is the gettydefs entries that I've added for the modem. It was
recommended to me to use these slightly modified entries and I havnt
experimented with the stock ones. I mean, these work. :-)  I then made
the entry in /etc/inittab  to specify "9600M" as the getty speed on
startup. 


9600M# B9600 HUPCL PARENB CS7 OPOST ONLCR # B9600 HUPCL SANE IXANY TAB3 #login: #2400M

2400M# B2400 HUPCL PARENB CS7 OPOST ONLCR # B2400 HUPCL SANE IXANY TAB3 #login: #1200M

1200M# B1200 HUPCL PARENB CS7 OPOST ONLCR # B1200 HUPCL SANE IXANY TAB3 #login: #9600M

  This is the Devices file. Again, I had to specify "direct" for the modems
so that dialing could be done manually in the Systems file. 


Direct	tty0	-	1200
Direct	tty0	-	2400
Direct	tty0	-	4800
Direct	tty0	-	9600


  This may seem like a lot of work but it's really quite simple. I beleive
you could use this method with conventional UUCP. The main reason for
going to HDB is to make use of the Dialers file, unfortunately this is
a problem. It sometimes takes a little thinking to configure a new site
in the Systems file, but I have now about 10 sites entered and working
reliably at anywhere from 1200-9600 baud. Once you see the method used
for spoofing a dialer, its easy to make changes. It actually quite neat.
I mean you can if you wish, make register changes on a per-call basis if
you have calls requiring special needs. I hope this information is of use.
