+# logging via a program on another computer (via network)
+
+The idea is that `rigctld` would connect to the radio via network. All
+other programs would connect to `rigctld`.
+
+0. Launch `rigctld` to connect to the tcp port of pihpsdr:
+
+```
+rigctld -m 2040 -r $IPADDR:19090
+```
+
+where `$IPADDR` is the ip address of the computer running pihpsdr.
+
+1. create a virtual pair of serial port.
+
+```
+sudo socat pty,link=/dev/vtty0 pty,link=/dev/vtty1
+```
+
+Here `vtty0` and `vtty1` are regular files and can be created anywhere
+in the filesystem. If it is in a non-privileged location, then `sudo`
+is not needed.
+
+2. run the ts-2000 rigctl emulation program `rigctlcom` so that it is
+   listening for TS-2000 commands on one end of the above serial port
+   parts and talks to rigctld natively on the other. On the other end,
+   you would connect a logging program or another program that expects
+   a serial/COM port.
+   
+```
+sudo rigctlcom  -m 2 -R /dev/vtty0 -S 115200
+```
+
+3. Now, as a test, open minicom, turn off hardware control off, set
+   the port to `/dev/vtty1` and type in `FA;`. It should display the
+   current frequency used by pihpsdr. Other programs like logging
+   programs can now connect to it.
+
+
+This is the basic idea. One can run all of these programs in a single
+computer or in multiple computers connected via network with the right
+configuration. `rigctl` and `rigctlcom` also takes a `-r` switch to
+specify the address of of the "NET rigctl" as the radio, provided a
+`-m 2` parameter is also passed to rigctl. Some knowledge of how the
+programs all work together is helpful when debugging issues.
