There are a number of products from various suppliers that give You more
than the 4 COM-ports that DOS allows, albeit with a special driver:
- GTek (see the back page of Circuit Cellar Ink)
- Chase (AT16 gives 16 serial ports).
These two I know of (we use CHASE ourselves).
There are bound to be more.
I have no connection with any of these companies. I'd loose my job if I
had!
