Hi,
Just a query. For Serial communication in a null modem configuration, how many level of handshake do you actually need?
Is it as follows:
For transmission side, you are supposed to send a DTR signal and wait for an DSR response. Then do you actually need to use the RTS and CTS pair if no modem is involved?
Thanks for your help!
