I have what is hopefully a simple problem with a MultiTech 224E modem
that's been loaned to our users group for a BBS system. In general, the
modem performs flawlessly, but on two occasions, both following brief
power interruptions, the modem has refused to answer incoming calls
despite the fact that S0 has been set to 1. In both cases the BBS was
kicked down by a local power interruption, came back up correctly, but
could not receive calls due to the state of the modem. The setup string
looks fine and works on all other occasions. I confirmed that S0 was set
to 1. In this state, the modem will dial fine, and will answer if forced
to by either the front panel or an AT command. Cycling the power on the
modem does NOT help, and it does not go away with time - on one occasion
it was not detected for 36 hours. Leaving the modem off overnight DOES
solve the problem. Unfortunately, I have no documentation for this unit,
but I notice that it does have a lithium battery onboard and suspect the
problem may revolve around that and perhaps a scrambing of non-volitile
memory. Is there a command that resets this memory that I could add to
the BBS startup sequence???   Does this unit in fact have some sort of
local battery backed memory ??
 
  Thanks.......
