!We do it for rates <= 2400 bps.  Our Telebit modems work okay through a
!DS200 for interactive work at the high speeds (192Kbps) provided you
!don't print too much to the screen at once, but we've not gotten UUCP
!to work at the fast speeds.  We're running a DS200 into a DS5400
!running Ultrix 3.1C.  When we upgrade to Ultrix 4.1 I'll try again,
!but rumour has it this just won't work:

This is a patch available for LAT which will allow to function at 19200
without dropping of characters.  Contact your CSC for the patch.

[For those interested, the standrad BSD tty driver contains too small of
a rawq clist to handle the packetized input from a terminal server.  So
we added an "overflow" clist to buffer the characters that would have
been dropped from the rawq.  These are then feed back in after a read
hasbeen completed.]
