Here is the experiment I did with my old DigiBoard:
I am using a Practical Peripherals PM288MTII V.34 modem.
The maximum baud rate of the modem is 115200.
bash# cu -l /dev/cuaa5 -s 115200
Connected.

Result: I got all the parameters of my modem and "OK" prompt
back.
Here is the experiment I did with PC/8e:
I am using the same modem as above.
bash# cu -l /dev/cuaD000 -s 115200
Connected.
at
(no respond)
Result: I don't get any respond back from the modem. No OK
prompt.
Here is the second experiment with the PC/8e and the same
modem, but lower speed:
bash# cu -l /dev/cuaD000 -s 57600
Connected.
