I'm writing a "driver" that will enable my existing application
to communicate with a device. Normally the device would be the DCE and the PC would be the DTE, which means the PC raises the RTS and DTR lines and the device raises the CTS line etc.
The problem is that the device's comms protocol is working as if the device is the DTE. So.. the device will not send data unless the PC raises the CTS line.
How do I raise the CTS line in my driver? I can only find funtions to raise DTR etc, but not CTS.
