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

COMMAND
        MHEARD -- List recently heard stations.

SYNOPSIS
        MH <portnum>

AVAILABILITY
        The MHEARD command is available to all users.

DESCRIPTION
        If the facility is enabled on the specified port, the MHEARD
        command lists the most recently heard stations on that port,
        along with the date / time of reception, the number of frames
        heard, and various other information (see below).

        This is useful for users to discover who else the router can
        hear, to aid the search for suitable digipeaters, and to
        diagnose problems.  Even on linking-only ports, where there is
        only usually one partner, it provides a useful indication when
        the frequency is being encroached, either by deliberate
        squatting, unauthorised attempts to link, or lift conditions.

        The command may be abbreviated to "MH".
