The
MCso
controls the receipt of data from a device
connected to SERIAL 1 via:
No handshaking protocol.
XON/XOFF or XPC software handshaking.
DTR hardware handshaking (raising and lowering the
DTR line's voltage).
Both hardware (DTR/DSR) and software
(XON-XOFF/XPC) handshaking.
When handshaking is active, the terminal handshakes
via SERIAL 1 when:
The receive buffer is 25% full.
The receive buffer is 50% full.
The receive buffer is 75% full.
When sending data to a device that is connected to
SERIAL 1, the terminal:
Ignores all Incoming software handshaking codes.
Responds to XON/XOFF software handshaking.
Responds to DSR hardware handshaking (raising and
lowering the DSR line's voltage).
Responds to both hardware and software
handshaking.
2
Software handshaking is XON/XOFF if Keycode parameter is set to ASCII, XPC if
Keycode parameter is set to scan.
3
Do not change the default setting unless another setting is specifically required. Set to
XON-XOFF for full DEC compatiblity when the
MC80
is operating in an ANSI emulation.
