Two way communcation with the serial port (modem to modem)
posted 4 years ago
I used rxtx example(TwoWaySerialComm.java) to open modem in A and B. A use at command connect to B by modem.
B can send text to A and B's text display in A's console after connected, but A can't send text to B. I don't know why.
Does anybody know?
