	I have been running SLIP just fine.  2.0R and Xfree3.1 runs
INCREDIBLY well!  Thank you to all the teams whose efforts gave me such a
great OS and GUI!

	However...


	When running SLIP, if I kill the connection (e.g. kill
slattach,  cu, then give an "ATH")  cu dies instantly, and I get 
ack to the tty  (tty01 in my case).  I  am not sure if its the tty
or the sio.  Here are the results of some test:

	If I do "stty -e -f /dev/tty01" I get nice results.

	I wrote a little ioctl program to look at the port, with the
description pointing to /dev/tty01.  All it does is return some settings
to a termios struct.  When  I run it for tty01 it just hangs.  When
I run it for tty00 (mouse port) it runs fine.

	Even rebooting again to FreeBSD doesnt fix it.  However, if I
boot to DOS nd run telemate, trying to get to the modem works just fine.
If I boot to DOS and then back to FreeBSD, things are fine w/ FreeBSD
once again.

	I have a 16550A for tty01 and a 16450 for tty00.

	Any ideas, comments, and of course solutions would be much
appreciated :)
