interesting..

kronstadt:~$ stty
speed 38400 baud; line = 80;
kronstadt:~$ stty 0
stty: standard input: unable to perform all requested operations
kronstadt:~$ stty
speed 0 baud; line = 80;
kronstadt:~$ 

the same result on xterm and a virtual terminal.  It looks like
cfsetospeed tries to set the speed to 0 _and_ twiddle the modem lines,
and the VT/pty driver's failure to do the latter is what the error
message refers to.
