COM port not working

I have a PC with the following specs -
P4 3.0gHz
ASUS P4C800-E
1gb RAM
Radeon 9600XT

I have a program P4000 that I use to exchange data between my PC and a RC transmitter. I can run the program in DOSBox but I cannot communicate via the serial port. I have tried this on another DOS PC and I can get everything to work there.

I have configured the port in the config file.
I have confirmed my port is working with other software (not in DOSBox).

Can anyone help me with this problem?

Thanks, George

Not yet I think. But there is patch on its way that might help you:

Probably. Type in config -writeconf dosbox.conf inside DOSBox. Exit from it and edit dosbox.conf using Notepad. Check for relevant configuration strings there. 😎

WTF?

1. What version of DOSBox are you using?

2. Try renaming your dosbox.conf first, then launching DOSBox and doing the writeconf thing. You'll get lots of helpful comments if you're using a recent version.

i follow your instructions, the comments removed by me, the code is shortest in this list...

The dosbox_cvs_serport_win32.zip is actually from February 2005 CVS.

I dowbload the latest (2005.04.25) cvs, extract to a folder, but when i start it, no sdl.dll error msg is present.
I copyed sdl.dll from dosbox 0.63 (stable) directory to the cvs program directory, but the com port don't work 🙁
The error msg in dosbox terminal:
Exit to error: set priority command not handled

What's the problem?
