Version 2.2 Revision July 1998 Document.  Note only  a maximum of six characters allocated for callsigns.

List of AX25 routing tips.

Useful to have a Map handy for location names and relate to node aliases.

When you arrive at the required node The following commands are useful.
 I     (information) command to hopefully find the QTH of the node

U    (users command) to see who is using the node links and software
        version being used by the node. E.G. BPQ TheNet

PO (ports) command to list the port to use to connect out via
            to connect to a station.  e.g. to connect via port2  c 2 callsign.

MH or H(heard) commands to find someone to talk to live on the
        require port at the remote end of the link
?        to get a command list

CQ     Some nodes have the CQ command which send out one packet
            e.g. CQ CQ CQ FROM SURREY UK PLEASE KKKKKK
A station seeing the relayed
CQ call, connects and the network establishes the connection back to your station     

Remember!! UNIX server commands are 'case' dependant, UPPER case letters are different from lower case.  So it's safer to use lower case all the time

NetRom Routing

Please advise of any nodes that no longer work on your journeys around the network.
Use the list as an example and make up your own and try to connect to a live station several hops away.  See if  the remote operator responds to your connection.
