The <direction> parameter sets which directions use the compression method.
The 56K Softmodem uses compression in one or both directions.
Table 3-64: Valid <direction> Values
The <max_codewords_tx> parameter specifies the maximum number of code
words to negotiate in the transmit direction. The <max_codewords_rx> parameter
specifies the maximum number of code words to negotiate in the receive
direction.
Default <max_codewords_tx> and <max_codewords_rx> value.
Valid transmit and receive code word settings.
The <max_string_tx> parameter specifies the maximum string length to negotiate
in the transmit direction. The <max_string_rx> parameter specifies the maximum
string length to negotiate in the receive direction.
Default <max_string_tx> and <max_string_rx> value.
Valid transmit and receive string lengths.
The <max_history_tx> parameter specifies the maximum length of the history
buffer to negotiate in the transmit direction. The <max_history_rx> parameter
specifies the maximum length of the history buffer to negotiate in the receive
direction.
