rsuplnk [-q] <port>
The rsuplnk program allows a user to gain entry into the ROSE network using the standard pseudo-digipeating method. Recent Linux kernels are aware of this form of operation and the ax25d program can listen for such connections. The normal mode of operation of a ROSE switch is to have one ROSE address (ie port) per physical AX.25 port. Therefore ROSE users coming in on a given AX.25 port will appear as if they come from the associated ROSE port. This is the reason for the need for a ROSE port as an argument.
To use rsuplnk you need an entry in ax25d.conf to listen for incoming connections. In the example below, I will be listening for ROSE connections on my AX.25 port 144 using the callsign KE4GAJ-10 and the ROSE port associated with the AX.25 port is rs144.

There would typically be one rsuplnk per user access AX.25 port. The associated program for exiting a ROSE network is rsdwnlnk.
All errors generated by rsuplnk are written to the system debug log file.
