RS232 Data Format

The online mode uses 1 start bit, 8 data and 2 Stop bits with NO parity with a
baud-rate between 1200 and 115,200. Ensure that the receiver is set to the same
baud-rate and data format.

The Comma Delimited ASCII data format can be directly input into a standard
terminal emulation program (e.g. Microsoft HyperTerminal) and can be saved
as a standard text file which can be exported to most spread sheets e.g. excel.
