digiboard - how to disable HW flow control under Linux?

We are using a AccelePort Xp 8p PCI DB25 on LINUX redhat and we have serious problems to make it work.

We are connecting a card reader on the serial port and not a simple modem.

It seems that we have a problem concerning the HW flow control.

We want to disable it, how is it possible?

Thanks for your help

To disable hardware flow control and enable software flow control:

cat < /dev/ttyG### > /dev/null &
ditty -ctspace -rtspace -crtscts ixon ixoff ttyG#

Add to a startup script to make the settings permanent after rebooting.
