i'm not certain the documentation doesn't say that EXTA works, however,
it does work.  i have used EXTA on SCO 2.2.1 on a '386 with a completely
stupid serial card at 19.2Kbaud with no problems.

i believe a quick look in the /etc/gettydefs files will reveal the
relevant settings for a 19.2Kbaud login line.  turning on the EXTA
bits in c_cflag with

	termio.c_cflag &= ~CBAUD;
	termio.c_cflag |= EXTA;

aught to get you there.  i don't know if EXTB will get you to 38.4,
since i don't have a terminal at home which goes that fast, but i
suspect it will.
