TERMINAL OPTIONS DATA FORMAT + ASYNC AT&M0 SYNC DATA AT&M1 DIRECT SYNC AT&M2 AT&M3 Operates as an asynchronous modem with data buffering, may work with data compression and/or error control. Fixed DTE speed with flow control. (Default) The modem accepts asynchronous commands, but changes to synchronous operation in data mode and exchanges data synchronously with a remote modem. Direct asynchronous mode without data buffering. DTE speed equals link speed. The modem accepts synchronous commands (V.25bis) and exchanges data synchronously with a remote modem. As an alternative, you can dial from the front panel or use a telephone set to connect. DATA FORMAT defines the methods your modem employs to exchange data with the local DTE and the remote DCE. CHARACTER LENGTH + 10 11 9 8 AT*C0 AT*C1 AT*C2 AT*C3 10-bit characters. (Default) 11-bit characters. 9-bit characters. 8-bit characters. Note: The character length includes the start, data, parity, and stop bit(s). COMMAND SET + AT AT*I0 V.25bis AT*I1 DUMB AT*I2 The modem accepts asynchronous AT commands. (Default) The modem accepts asynchronous or bit-oriented synchronous V.25bis commands. No commands will be accepted. The modem ignores the DTE data in idle state. Note: Only asynchronous commands are accepted on the parallel port or internal card DTE interface. 6-3
