I have a terminal hooked up to the coco under Os9 level II. It is in slot
one, with an RS-232 pak. It runs 19.2 kb. I also have a modem hooked up
in an RS-232 pak, slot two, running 1200 b. When I config'ed a disk with
both /t2 and /t3 on it, there was an unacceptable bug: Anything
sent to either port also appeared on the other port, and at the baud rate of
the intended port. So, if I sent a string to the modem, then it would get
there OK, but the terminal would display a load of junk which must've been
1200 baud, since one string expanded to half a screen on the terminal. Also,
sending anything to the terminal causes the modem lights to flicker at 19.2kb.
(They of course don't recieve anything.)
Can anyone tell me what I can do to fix this problem? Send new dd's, if I need
them. (I know ~zilch about device drivers/descriptors) I can't use /t1 for the
modem because it slows the system almost to a halt, and I also want my printer
online.
Thanks in advance,
Jon

[Description of data going out to one pak going to both on his L2 system]
As with the 300bps modem pack drivers (/m1 and /m2), /t2 and /t3 cannot be
used at the same time. Why? They both use the ACIApak driver under L2, so
any data that goes out to either one is run through that driver. The only
difference between /t2 and /t3 is which slot of the MPI the RS-232 is in
(since 1 and 4 have the hardware support for interrupts and slots 2 and 3
do not). This, unfortunately, is a silly oversight on the part of the Shack
and/or Microware. [This information is taken from the old L1 update package
that was put out before the CC3 for various compatibility reasons.]
