PAD Parameters


PAD parameters control the display and transmission of data over the packet-switched network.

Parameters are of two types: PAD Parameters and National PAD Parameters. There are 22 PAD parameters (1-22) and an additional set of National PAD Parameters offer configuration options. National PAD Parameters (numbers starting at 70) support and control the enhanced functionality provided by the Hayes X.25 feature. All parameters are set and read the same way.

Values for some parameters are calculated by adding the bit values of the options you want active. For example, in PAD parameter 3, if you want the character set to include A-Z, a-z, 0-9 (bit value=1) and CR (bit value=2), you would set the PAD parameter 3 to 3.

A marker (0:0), called a National Marker, separates the National PAD Parameters from the PAD parameters. For example, in the PAD command: SET 1:1, 2:0, 0:0, 70:1, the characters to the right of the marker refer to National PAD parameters. Characters to the left of the National marker refer to PAD parameters.
