Displays or modifies the destination callsign, and digipeater
path for the regular AX25 "ID" beacons. The default setting
is "ID" with no digipeaters. You may wish to modify this, for
example on APRS ports, to digipeat your beacon.
If "path" is not specified, the current path (i.e. destination
and digipeater callsigns) is displayed.
If "path" is specified, the IDPATH parameter for the specified
port is changed to the new value.
The "path" argument should be supplied in the form
<destcall>[,digicall,digicall,...]
where <destcall> is the destination (i.e. "to") callsign, and
[digicall] are optional digipeater callsigns.
The minimum abbreviation of this command is IDP.
