This is the signal ground terminal.
The transmit
data
is the serial data from
the
transceiver to the computer.
The output utilizes
negative logic.
The receive data is the serial data from the com-
puter to the transceiver.
The input utilizes nega-
tive logic.
This signal is supplied from the computer, and is
used to inhibit transmit data from the transceiver
when the computer is not ready to receive.
The
input utilizes
positive
logic.
(Transmit
data
is
stopped by a logic low.)
This signal is applied to the computer, and is used
to inhibit transmit data from the computer when
the transceiver is not ready to receive it. The out-
put utilizes positive logic.
(Inhibit is requested
when the level is low.)
