Hello.
   The NeXT serial ports are not limited to 9600 baud. The NeXT serial
ports will run at 19200 baud and 38400 baud. The 040 can't maintain
38400 without hardware flow control. The situation is even worse on
an 030 because there is no flow control and the CPU speed is so much
slower. The 030 does at best 9600 baud.
   Not only are the serial ports slow, but doing high speed transfers
(>= 9600 baud) greatly degrades system performance.
   If these problems are causing you grief, you might be interested
in TTYDSP. TTYDSP is an inexpensive hardware/software product, which
uses the DSP to drive a high performance serial port, which has none
of the problems of the standard ones! If you'd like further information,
please contact me.
