There are two methods to configure COM port.
1. you allow direct access to the hardware: 8 I/O addresses,
and passing an irq to dos programs.
2. you specify /dev/cua0 or similar to be virtual port.
I suppose 1 allows full control, and has disadvantage it
lacks buffering - you can lose data while other tasks are
active. 2 gives you less control (I suppose you cannot set
baud rate, send break, ...), but Linux can buffer the data.
Try both methods to diagnose the problem.
Note in DOS there are memory locations for COM port I/O
addresses: 40:0,2,4,6 (4 words for up to 4 COM port).
Make sure there is something there (I/O address for 1).
