SW-Handshake – Software handshake protocol
Besides the hardware handshake mechanism using interface lines, it is also
possible to achieve the same effect by using a software handshake protocol.
Here, control bytes are transmitted in addition to the normal data bytes.
These control bytes can be used, as necessary, to stop data transmission
until the receiver is ready to receive data again.
In contrast to hardware handshaking, software handshaking can be realized
even for a simple 3-wire connection.
One limitation is, however, that software handshaking cannot be used for the
transmission of binary data, since the control characters XON and XOFF
require bit combinations that are also used for binary data transmission.
Default setting is NONE.

Owner – Assignment of the interface
The serial interface can be assigned alternatively to the measuring instrument
section or to the computer section
If the interface is assigned to one section of the instrument, it is not available
to the other section.
INSTRUMENT The interface is assigned to the measuring instrument
section. Outputs to the interface from the computer
section are not possible will get lost.
OS The interface is assigned to the computer section. It
cannot be used by the measuring instrument section. This
means that remote control of the instrument via the
interface is not possible.
