Include "modedefs.bas"  ' Include serial modes

SO Con 0                ' Define serial out pin
SI Con 1                ' Define serial in pin
B0 Var byte

mainloop:
   Serin SI,N2400,B0    ' B0 = input character
   If (B0 < "a") or (B0 > "z") Then print  ' If lower case, convert to upper
   B0 = B0 - $20

print:
   Serout SO,N2400,[B0] ' Send character
   Goto mainloop        ' Forever

   End
