- First is it possible to set up more than 2 serial ports in dos box
I would like to forward 5 dos box serial ports to 5 real serial ports on the host pc.

- Second if possible how would i go about doing it where can i find info regarding serial port configuration. I have not been able to get more than 2 to run at any one time. am i missing something simple. I have not found any other info regarding setting up more than 2 serial ports. Any suggestions on where to find info or examples would be greatly appreciated.

I am running win xp and ubuntu 10.04lts on the host machine

thanks in advance for any help and thanks again for letting me relive my glory days playing old and forgotten games.

No more than 4. You may have to specify different interrupt lines for ports 3 and 4 depending on the DOS application.

thanks for the answer to my question. Just out of curiosity why is there a 4 port limit?

Didn't real DOS have a 4 COM port and 3 LPT port limit too unless you use both special hardware and special, made-for-that-specific-hardware software? Because that's how much space there is in some fixed-address tables in low memory, if I remember correctly?
