Btw, how to make the BS2 send the data logged (temperature values) using its serial port to PC?
Please advise. Thanks in advanced.

More info please. You use serout or debug to communicate to the PC. What is it exactly that you are trying to accomplish?

BS2 sense the temperature and log the value in its eeprom. I want to send these value to PC through BS2 serial port, so the program on PC, can record and follow up these data. Can I do it? or have to use one of BS2 port as a "serial port", for using with SEROUT command?

You can use the DEBUG statement or SEROUT statement with pin #16 to send data over the programming port. There are some restrictions: 1) The Baud is limited to 9600; 2) Anything sent from the PC is echoed back to the PC; 3) When the serial port (from the PC) is opened, the DTR line is set true. This resets the Stamp. It's part of the programming process.
Have a look at Stamp Plot Pro (www.selmaware.com (http://www.selmaware.com)) as an example of a program that can be used on the PC side to log information from the Stamp (and graph and analyze it if you wish).
