Option 2
Assignment (SASI) in the user program (the port must not be
conguredasS-BusPGUport)
If a programming device is connected again instead of the
peripheral device during operation, the mode is automatically
switched over to PGU (pin 6 logic 1 (DSR), in PGU mode:
DSR PING = 1)
In order to be able to use the interface again for the

1) When communicating with terminals, check whether certain connections are to
be bridged or to be set by the command SOCL on 1 or 0. Generally the use of
handshake (RTS / CTS) is recommended (see also manual 26/795, series PCD7.
D23x, graphics terminals).
Option 3
Port 0 can also be used as a modem interface with a 1 to 1 ca-
ble. As described in chapter 7.1.2 Hardware options, the check
box Full RS-232 handshaking on port 0 must be selected.
Option 4
With connection cable PCD8.K111, this interface can be used as
a programming device connection.
