Using the AT Command Set
CSMIM-T1 Hardware Installation Guide 6-5
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.
6.3.2 Establishing 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.
