MNP Operation
The SE1440 supports all of the preceding classes. The following AT Commands apply to
the MNP protocol. Default values are highlighted.
Command Description
Maximum MNP Block Size. Use this command to transmit smaller blocks of data in a
reliable data link connection.
AT\A0 set maximum block size to 64 characters.
AT\A1 set maximum block size to 128 characters.
AT\A2 set maximum block size to 192 characters.
AT\A3 set maximum block size to 256 characters. (DEFAULT)
Transmit Break. When this command is entered during a non-MNP connection, a
break signal is sent to the remote modem. The length of the break is 100 times the n
parameter (1-9) in milliseconds. The default is 3.
AT\B3 (DEFAULT)
Modem to Modem Flow Control. Enables or disables modem to modem flow
control during a normal mode connection. This command is ignored when error
correction is selected.
AT\G0 Disables flow control (XON/XOFF) (default)
AT\G1 Enables flow control (XON/XOFF)
BPS Rate Adjust Control.
AT\J0 Disabled. Serial port speed is independent of the connection speed,
which allows much greater throughput when using error correction and
data compression. (DEFAULT)
AT\J1 Enabled. If enabled, the serial port speed will automatically be changed to
the modem connection speed.
