This option allows the user to transmit the printed results to a host computer
via the external PC port.
To select this option via the LCD display, refer to Chapter 7.3.3.
The PFA-100 System transmits each result with a checksum. The format for
the checksum line is: cs: nnnnn<LF><CR>. It is the responsibility of the user
to ensure that the data received by the host computer is accurate. To do so,
the communication software used by the laboratory should have the
capability to calculate the checksum value by adding up the transmitted
characters one byte at a time, starting with the first character of the header
until the last character before the checksum line. The checksum is a two-
byte module 65536 value. Each line has a <LF><CR> at the end.
