# This script makes it possible to view and copy files to/from a hp48
# (tested with a HP48G and the emulator x48)
#
# To use the hp48 external filesystem:
#      - read the relevant parts of your HP48 manual
#      - install kermit
#      - connect the HP48 to your computer or start x48
#      - below change the line which reflects the serial device you use
#      - configure your HP48 (<left shift> - i/o - iopar): 
#        port: wire
#        baud: 9600 
#        transfer format: binary (fast transfers) or
#                         ascii (editable on the pc)
#      - start the server on the HP48: <left shift> - i/o - srvr - serve
#        or the shortcut <right shift> - <right arrow>
#      - on MC's commandline enter "cd hp48:"
#
# Make sure you have kermit installed and that it's using the right serial
# device by changing /dev/ttyXX on the next line
