You need to edit the file space.c in /etc/conf/something/asy and add two
more lines
for com3 and com4. I did it long time ago and don't remember exactly
what to do.
I don't run ESIX anymore so I can't look it up.

Adding the devices won't do it. The device driver only support two
serial ports.
That's why you need to edit space.c file and add more devices.

Good luck.
