trouble with xbee

I worked last night on trying to·setup the appbee module·on one of my BS2 carrier boards. I had a BS2SX module in the board and I had one of the Maxstream usb boards hooked to my PC. I programmed both xbee modules with the latest 1083 firmware.
When I try to run the sample code to send a character from the stamp and appbee to the PC board I receive characters on the maxstream terminal window but they aren't what I've sent. I initially thought it might be a transmission or baud rate problem·but I'm getting the same characters consistently and I would imagine they would be somewhat random with a transmission problem. I've tried sending text, dec, hex. Doesn't seem to matter. When I send different characters·the recieved characters on the other end sometimes change but there's no one for one correlation. Other that this everything appears fine. When I reset the appbee the transmission stops. The transmissions are in sync with the basic program I have the character debuged to the screen before it's serout line.
I'll keep reading and troubleshooting but maybe someone has seen this and can narrow down my troubleshooting.

I was trying just the most basic code below with a few variations to try different characters and DEC and Hex numbers.
Thanks Joel
RX PIN 0 ' Receive Pin
TX PIN 2 ' Transmit Pin
X VAR Byte
HIGH TX ' Idle transmit pin
DO
X = X + 1
SEROUT TX,84, [noparse][[/noparse]DEC X,CR,CR] ' Send value of X as decimal
' Second CR is added byte buffer for flow control example
DEBUG X
PAUSE 500
LOOP

I will try 240 and let you know. I also thought about changing to a straight BS2 processor to see if that had any impact. My next check will be to re-setup and do a loop back check on the xbee modules just to confirm that they are still configured to talk correctly.
I appreciate the help.
I changed 84 to 240 with the sx chip in and works perfect. When I send a decimal number to the xbee board on the PC the corresponding ascii char for that number is displayed on the terminal.
Thanks for the help. Saved me a lot of frustration. I guess the clock speed on the sx changes the constant.
