modem into Command mode, as well as set the serial port to 9600 baud, 8 data bits, one stop, and no 
parity.  If the baud-rate was OK, verify the AT, BT and CT times, that they are long enough for you to 
enter the +++ string.  

Solution #2: Handshaking.  You may have hardware handshaking enabled on your terminal program, but 
the hardware or cable may not support it.  Disable hardware handshaking on your terminal program to 
verify this is the issue.    

Solution #3: Deep Sleep.  If the TXRATE is greater than 60 seconds, the unit may be put into a very deep 
sleep mode, and will not enter the command mode.  You must first turn the unit off, and back on to put 
it into Command mode.
