THE MESSAGE TERMINATING CHARACTER
The message terminating character is a single character
that indicates a complete message has been received in
immediate and command reporting modes. Data is held
in the buffer of the M Series unit until the terminating
character is received from the connected peripheral
device which defines a complete message. The
complete message is eventually sent to the host device
depending on the mode of operation. The message
terminating character can be programmed to be any
two-digit hexadecimal character from 00 Hex to 7F Hex.
The factory default message terminating character is 0D
Hex (Carriage Return).
