Appendix C: Synchronous Modes

This section explains the use of your modem in synchronous
modes. A dumb mode or manual mode allows some of the
functions of your modem to be accessed via the front panel
switches.

Your modem offers two synchronous modes, conforming to the
Hayes modem synchronous modes 1 and 2. These modes
allow synchronous communication over two-wire PSTN or
leased lines when connected to asynchronous/synchronous
computers or dedicated synchronous terminals.

Synchronous Operation

Your modem supports two synchronous modes. Mode 1
allows operation with computers which support asynchronous
and synchronous communication on a single RS-232 port.
Mode 2 allows your modem to be operated with dedicated
synchronous terminals.

Although your modem can only operate over a single two-wire
connection, it will still perform full-duplex synchronous
communication. Half-duplex operation could be simulated by
controlling the state of the RTS and CTS signals.
