The E5AF RS-232C is defined as DTE (Data Terminal Equipment). This
means that a carrier detect (CD) signal for the host computer is not sup-
ported. If a CD signal is needed, it must be provided (via the +12 V terminal)
on the host computer side.
The communications specifications of the E5AF are the same as those of the
E5AX, except for the commands that are used for the fuzzy function of the
E5AF.

Communications and Error Control
The communications protocol for the E5AF/E5EF is a special conversational
type. The first right to send belongs to the host computer, and the right is
transferred with each block sent. Whenever a command block is sent, a re-
sponse block is sent in return.
