[App_rpt-users] Anyone using MDC1200 for control?

The new version of app_rpt.c which will be posted on SVN
this evening contains new code (experimental at this point)
which allows you to put a '[mdcmacro]' stanza in your rpt.conf file
where the entries under it are UnitID=DTMF Tones To RUN

So, like:

[mdcmacro]
d00d=*32000

If you have id d00d, it logs into hub node 2000.

If you send the same ID over and over again, it ignores
subsequent duplicates.

If someone would find me a full copy of the MDC-1200 command
set, I sure would appreciate it.
