ComForceXon

This function deasserts flow control to the remote transmitter.

ComForceXon permits the remote transmitter to resume transmission. If XON/XOFF flow control is used, then ComForceXon sends an XON. If RTS/CTS flow control is used, then the function raises RTS. If DTR/DSR flow control is used, then the function raises DTR.

If the port does not have a flow control method selected, this function is a no-operation.
