I've a 386DX40 here with 1.2B kernel and 1.1 everything else.  It's running
great in all respects, *but*...

In attempting to attach a 9600bps serial terminal with null modem to a
serial port (16550 based com1), I get what appears to be a bunch of $FF
chars.  I can't find my serial analyzer, but that looks like the getty is
constantly sending a BREAK to the line.  I've fiddled with various null
modem setups with no luck (in fact, a 1-1 7-7 2-3 3-2 cable causes getty to
exit, restart, exit, restart so fast that init puts it on hold).  The port
works great; it was (and still can, if I slattach) attached via slip to
another machine at 57.6k, and the ttys entry is using the proper gettytab
entry (std.9600).  With NetBSD/amiga, std.9600 seems to do exactly the right
thing; with /i386, !? 

Do I need a funky null modem setup to get this to work?  Does anyone else
have the same problem?  (Is there any way to tell the com port to ignore
control lines altogether and just shove and receive data blindly on 2/3?)
