You can't. The BS2 'run-time' environment is programmed onto a PIC. Your program is tokenized, and downloaded into an EEPROM on the BS2 module.
There is *no* code on the BS2 'run-time' which will let you read the EEPROM off the BS2.
Now, you could write a program for the BS2 which would read *itself* and send the tokens back to the serial port to the PC under visual basic -- but unless you wrote this program (using the READ call to read eeprom, and SEROUT to send it back to the PC) you can't read the BS2 eeprom.
