Reply-Path:

I am interested in finding out two pieces of info concerning modems
and Ultrix - currently 1.2, some day 2.?.

1.  How can we set up a Microvax II using the Dec serial board (I
dont know its name right now - sorry) to handle 9600 baud; I have
been told that it will lose characters at this or higher speeds?

2.  Is there ANYWAY that we can set up the system so that a naieve
user, coming in to a modem capable of autobauding, can have the modem
and unix automagically determine the caller's speed and adjust itself
to this speed?  Currently, we have things set up where the user has
to send a break to change baud speeds.  I would like to find a way
for the software to determine the baud rate by looking at what the
user is coming in as - perhaps with a return if necessary.

Thanks for any info.  Locations of appropriate code, books, magazine
article references, etc.  all all apreciated.  Locations for code
need to be accessible via mail or uucp though.

Thanks again.
