(!!ERROR!!)
When an incoming SMS contains an error in the
message format, no action will be taken by the unit
other than to send an error message back to the
calling mobile along with a copy of the erroneous
message itself.
Texts will be sent to mobile phone numbers stored in
PNUM on reboot after a power failure or reset (when
power is reapplied).
Note this feature is enabled or disabled by simply
either having mobile phone numbers in PNUM or not.
