Parity
Use this function to specify the parity for serial communication. The standard
parity defined for NMEA serial line communication is "None".
A parity bit, or check bit is a bit added to the end of a string of binary code
that indicates whether the number of bits in the string with the value one is
even or odd. Parity bits are used as the simplest form of error detecting code.
[...] In serial data transmission, a common format is 7 data bits, an even parity
bit, and one or two stop bits. This format neatly accommodates all the 7-bit
ASCII characters in a convenient 8-bit byte. Other formats are possible; 8 bits
of data plus a parity bit can convey all 8-bit byte values.

Communication with external devices is important for ES80 operation. The
communication between the Processor Unit and peripheral devices takes place using
"datagrams". These datagrams are self-contained and independent entities of data
carrying information. When setting up or maintaining the ES80, it is always useful to
verify that the communication lines with external devices are operational. The
dialog box allows you to study the communication stream on the chosen serial
Monitor
line or LAN port.
