(1) Header
You may select either "No header" or STX.
(2) Terminator
You may select ETX, CR, LF, or CR LF.
(3) BCC
Every parity bit of BCC (block check character) is set so that all set bits at the
same bit level (including a parity bit) in the characters contained in the transmis-
sion block have an even number by exclusing-ORing. Those characters do not
contain a header but include a terminator.
You may select whether BCC will be transferred. Note that BCC cannot be
transferred if the transmission block contains no header.
