Hello,

I tried to play OMF via virtual modem, and failed like the next person since DosBox doesn't handle int 14h.
I even tried to debug it myself and saw that OMF tries to initialize the UART with int 14h function 0.

Anyway, I couldn't find evidence on the forum that this issue is being handled, so I thought I might give it a go myself and add support for int 14h.
The only problem is, I don't know where to start.
Diving into your code isn't simple, so some documention on the verious parts might help.

Please don't bite my head off if I missed it.
