The M1XEP sends the following ASCII command out to all socket connected devices when ELK RP,
Upload/Download Software, disconnects from the M1:
08RP000036<cr><lf>. ELKRP disconnected broadcast.
The M1XEP replies to any poll when ELKRP is connected to the M1:
08RP010035<cr><lf>. ELKRP is connected, poll reply
The M1XEP replies to any poll when the M1XEP is initializing after a powerup or reboot:
08RP020034<cr><lf>. M1XEP is initializing after powerup or reboot.
