Hi all, I have successfully run a SLIP link between two machines over their serial ports. We now want to replace the null-modem cable with a radio at each end connected to the serial port. We also want the ability to "drive" the radio i.e. use flow-control based on the modem signals on the radio. Can anyone enlighten me about the facilities offered by the kernel to control the various RS-232 lines from kernel-space or user-space? Any pointers would be helpful.
