Protocol Specific Configuration

Predefined Configuration Values

The following configuration values are currently defined for use in

HDLC/LAP-B (ABM) configuration as a replacement for the POLL and

SELECT address fields. These values are used (for example

HDLC_DTE_3.0) as a symbolic way of configuring the associated two

16-bit hexadecimal values.

If a particular desired configuration value is not provided by these

values, then two hexadecimal values can be used instead (as for normal

poll and select specification).
