I read in your old mail today that you can change the speed of your
connection to a TAC with the @D R command. To set it to 300, you do
@D R 373, for 600, @D R 438. Some Bell 103 compatible modems, it was
pointed out, are capable of 600 baud.
I tried this, on the dialup connection between my vax and the MITRE-
TAC. It almost worked. The Vadic 3451 triple modem on my vax can
understand 600 baud using the Bell 103 protocol, but the modem at the
TAC couldn't understand the 600 baud coming back at it.
No problem, says I, I will use SPLIT SPEED and send to the TAC at 300
but recieve at 600! The command @D R 437 should set up the TAC end to
do this, and SET TERMINAL /SPEED=(600,300) TTD5: should do the right
thing on the vax end.
It didn't work. So I tried SET TERMINAL /SPEED=(300,600) TTD5:.
Still no luck. A little fooling around with a VT100 proved to my
satisfaction that the vax command SET TERMINAL /SPEED=(m,n) is
always interpreted as SET TERMINAL /SPEED=n. What a lose!
I am doing something stupid? Is this a known VMS bug? (We are
running V3.1). Shoudl I call DEC?
Tomorrow I will try using SYSTEM SERVICES to try to do the split
speed without messing with grody DCL. More news as it happens!

What kind of terminal interface do you have? TTs (as opposed to,
say, TXs) are usually DZ-11s which are INCAPABLE of split speed
operation.
