MAXFRAME(1)             XR32 REFERENCE MANUAL                19/1/2013

COMMAND
        MAXFRAME -- Display / Set port MAXFRAME value.

SYNOPSIS
        MAX[FRAME] <port> [n]

AVAILABILITY
        MAXFRAME is a sysop-only command.

DESCRIPTION
        The MAXFRAME command is used to display and set the AX25 L2
        MAXFRAME (window) value for the specified port.  This is the
        maximum number of unacknowledged frames allowed before the
        link must stop and wait for an ack.  The normal range is
        between 1 and 7, although maxframes of up to 127 are allowed
        in modulo-128 links.

        If the second argument is ommitted, the current value is
        displayed.

        If the setting is changed, the new setting remains in force
        until it is changed again, or until the router is restarted,
        in which case it returns to the default value specified in the
        port entry in the XROUTER.CFG file.

        If the port PACLEN is set to 0, XR32 dynamicallys adapts
        MAXFRAME (and PACLEN) to the link conditions, to maximise
        throughput.

EXAMPLE
        MAX 2       - Display current maxframe setting for port 2
        MAX 2 6     - Set maxframe for port 2 to 6.
