You are ready to establish a connection as either a dialing modem or an auto-answer modem. For tone dialing, type:

ATDT <telephone number> <Enter>

The modem automatically answers calls on the first ring if DTR is present.

Hanging Up

To hang up, use one of these methods:

•Pause 1 second. Then type +++ to enter command state. Type ATH <Enter> to hang up OR

•Lower DTR with your communications program when &D2 or &D3 is set.

See Chapter 7, AT Commands and Registers, for detailed information about any of the commands mentioned above.

6.3.2Establishing 11-Bit Data Connections

By default, your modem port passes 10-bit characters during MNP or LAPM connections.

In a normal or direct connection, those bit and parity settings on the originating and remote modems must match for data to transfer accurately. The serial-port parity determines the number of data bits set during a direct connection.

The -E command determines the characters handled on the modem port during a normal connection - unless the modem falls back from a reliable connection (either \N3 or \N5 is set) to a normal connection. In this case, the remote modem port must be set for a data length of 10 bits.
