I am trying to use DOSBox to run a software that is used to control a CNC machine. This program is used to feed the instructions for the CNC machine via a serial connection. The problem I am having is that the CNC controller is unable to stop the data once the buffer is full. Apparently the flow control is off.

Is there a way to set the flow control from within DOSBox's config file?

The correct settings for this program are:
9600
N
8
1
Hardware

Any help would be greatly appreciated.

Chris

DOSBOX is for games, not applications. You'll probably have to find some other emulator to run your machine.

The handshake is passed through to hardware.

1+1=10

If you're using a USB-to-serial adapter, in my experience those devices frequently have dodgy flow control. You might have better luck with a PCI serial board.

Thanks for the replies. I'm using the serial port built in to the mother board. Everything works as it should except for the flow control.

I know this is a 4 year old thread, however I do not believe that UART handshaking is passed. I can see DCD transitions in Linux, but not in DOSBox.
