  Its been a while since I have used a xbee but if I remember correctly delays are needed either side of the +++.
  I think there is a xbee object on obex why not check that for what happens with +++

  You need a three second guard time on either side of the "+++" in the XBee's default mode.

  I am trying to change the channel of an XBEE module using serial transmissions. I know this is possible but it does not seem to be entering into config mode with my code (it just transmits the plus signs to the receiver).
  
  

  SERRF.STR(string("+++", 13))                          '+++ puts the XBEE into config mode but it does not.
  SERRF.STR(string("CH", $C, 13, "ACTN", 13))    'These commands should change the channel.
  
  

  
  

  In addition to the other comments take a look at the XBee_Object object.

  As it encapsulates the delay around the "+++".
  

  Example code for starting:
  ' **************************
  OBJ 
      XB : "XBee_Object"       
  Pub Start
      XB.start(7,6,0,9600)           ' XBee Comms - RX,TX, Mode, Baud
      XB.AT_Init                     ' Initialize for fast AT command use - 5 second delay to perform
      XB.AT_ConfigVal(string("ATMY"),$5) ' Set MY address to 5
      .
      .
   
  

  
  Note you need to send just "+++" with the proper guard times before & after it. Your sample is sending +++ plus a carriage return.
  
  Hope this helps

  Beside the aforementioned guard times, take out the carriage return character after the "+++" as this will spoil the config mode command
