	Is it possible to use a Hayes compatible?
	....

    I am currently using a Hayes smartmodem 1200 in
    autoanswer mode and it seems to work pretty well
    with the following reservations:

    (1) I had to modify the defmethod (:dial-the-phone hayes-modem) in
    modems.lisp to get my modem to use dial tones rather than pulse dialing.
    I was told how to accomplish this same result by changing the subnets
    patterns, but I forget how to do it.

It's documented in the 8.0 hardcopy documentation.  You stick the appropriate
punctuation characters for your modem in the string after :DIAL for the given
entry in your SYS: SITE; SUBNETS.LISP file (and no, this won't work pre-8.0).

    (2) Frequently, my system gets into a state where it is not possible for
    me to successfully probe Riverside.   My modem goes off hook, dials,
    Riverside answers, and I see a carrier detect.  However, the carrier is
    then immediately lost.   This seems to be a Riverside-specific problem
    as I can successfully dial up other (non-Symbolics) computers.
    I'm currently working with Symbolics software support on sorting out
    what's going on.
    (any suggestions?)

    Regards,
    Joe

I'm currently investigating some bugs in Riverside's serial handling.
These bugs are in software that is not yet out in the field, so customers
won't be running into them except as victims of Riverside's occasional
lossage.  You've probably noticed that, except for a couple of days of
flakiness, Riverside appears to be back on the air, right?
