You have to change - edit G: and P:
Cause by default MGCAMD running with newcamd protocol.
G: 32 or 33 # (32 cccamd netclient, card list saved as /tmp/cccamd.info )
P: 02 # ( 02 cccamd, newcamd, camd3, gbox, radegast)
On this set you can read first cline....
I dont use anymore mgcamd, but if you still got problems message me and i will sent you my working backup conf.
Thanks for your reply M8, atm in my mg_cfg i have G: { 33 } and P: { 00 }, i will change value as per your suggest and i'll report here my test.
