2. ECC Command Set

COMMAND
AT%Cn Enable/Disable Data Compression
Enables or disables data compression negotiation.The modem can
only perform data decompression on an error corrected link. The parameter
value, if valid, is written to S41 bits 0 and 1.
AT%C0
AT%C1
S46 bit 1.
AT%C2
AT%C3
compression.Sets S46 bit1.(Default)
AT\An Select Maximum MNP Block Size
The modem will operate an MNP error corrected link using a
maximum block size controlled by the parameter supplied. The parameter value,
if valid, is written to S40 bits 6 and 7.
AT\A0
AT\A1
AT\A2
AT\A3
AT\Bn Transmit Break to Remote
In non-error correction mode, the modem will transmit a break signal
to the remote modem with a length in multiples of 100ms according to
parameter specified. If a number in excess of 9 is entered, 9 is used. The
command works in conjunction with the \K command. In error correction mode,
the modem will signal a break through the active error correction protocol,giving
