To restore the modem back into the AT command mode just send +++ and wait 3 seconds with no communications (Rx/Tx) activity. This "+++" is known as the "escape sequence" - as it causes the modem to "escape" to command mode. It actually needs silence both before and after the "+++" - the "guard time" - and the "+++" have to be typed in quick succession. Both the character used and the guard time are usually configurable via S-registers. |
