I have heard that flow control can be applied to virtual ports independently, but because HW flow control is the only available option when using CMUX, I don’t see how this is possible. Surely flow control would be applied to all virtual ports at the same time? Have I missed something in the documentation? Thanks in advance for any replies!
The individual hardware flow control at the application side (virtual serial ports/instances) are transmitted individually on each instance to the other CMUX end by means of V24 MSC commands (Modem Status Command) which are answered with the same V24 info, so the individual hardware signals are transferred by means of software data packets.
See CMUX User Guide doc for more insights.
OK, I see it now, many thanks for the information!
