I believe the examples on Bruce's website are sending data through the serial port to a VB written application that does the ASCII conversion, not to hyperterminal.

If you want to send to hyperterminal (examples)

Code:
X = 65
Serout GPIO.5,N2400,[65] 'sends "A" to hyperterminal
Serout GPIO.5,N2400,[#65] 'sends "6" and then "5" to hyperterminal
Serout GPIO.5,N2400,[X] 'sends "A" to hyperterminal
Serout GPIO.5,N2400,[#X] 'sends "6" and then "5" to hyperterminal
