Trailblazer in my stocking

[Kevin O'Gorman]

Well, I wasn't paying attention when you folks were discussing how to set
up your 'blazers to run with the UNIX PC.  Now I have found a shiny new modem
in my (?xmas?) stocking, and I'm having a little bit of trouble.

I think I have most of it set up right, and I have two phone lines to test
it with, but it looks like it's only half right.  I have the interface speed
locked at 9600 baud, and I call out with ATE, and listen with uugetty.

When I call out on the 'blazer to my OBM, everything seems to work fine.

When I call out on the OBM, I have what looks like flow control trouble.  The
login sequence doesn't even make it right.  What I type is okay, but it looks
like the computer (at 9600 baud) is going faster than the modem can push them
bits to a 1200-baud OBM.

Here's how it's set up

E0 F1 M1 Q0 P V1 X1     Version BA4.00
S00=001 S01=000 S02=043 S03=013 S04=010 S05=008 S06=002 S07=040 S08=002 S09=006
S10=007 S11=070 S12=050 
S45=000 S47=004 S48=000 S49=000
S50=000 S51=004 S52=001 S53=003 S54=003 S55=003 S56=017 S57=019 S58=003 S59=000
S60=000 S61=045 S62=003 S63=001 S64=000 S65=000 S66=001 S67=001 S68=255 
S90=000 S91=000 S92=000 S95=000 
S100=000 S101=000 S102=000 S104=000 
S110=255 S111=255 S112=001 
S121=000 

The blazer is on /dev/tty000, and I notice there's nothing for it in
/etc/daemons, like there is for /dev/tty000 and /dev/tty001.  I can't find
the documentation for /etc/hfc_ctl, so I don't know what this means, but
it sure looks like flow-control to me.  For a variety of reasons, I have
to fiddle all such stuff by hand, so the lines are not automatically
configured right.  Could the 'blazer be sending xoff, and the line be
ignoring it?
