Here's the code to detect a bill :


ON COM(1) GOSUB getbill
          credit = credit + 1
The above adds one bill(credit) for every character in the buffer. One (1) char per bill, five (5) chars for a five dollar bill etc.  *Should* check for Valid input:
HEX(0xF8, 0xFC, 0xFE) BIN(1111|1000, 1111|1100, 1111|1110)


REM DTR to turn the BA on/off:
      OUT &H3F8, 1    'ON
         REM where &H3F8 is your UART comm port (not USB)
      OUT &H3F8, 0    'OFF
If there is still an interest in the BA2PC (bill acceptor to Personal Computer) with Qbasic, please contact me.  We aren't supporting the QBasic formally, but I really miss it.  Supporting non-profit programmers with open source code.  We've still got archived notes and source code.  If you have any questions contact me.  Any new source I'll post it.
