OPERATION
PARITY
The available parity options are: space, odd,
even,
or mark
(continuously
on).
You can change the parity (illustrated as
space in the sample) by pressing
the~
key, which will change
the parity to the next selection and display it. If you do not want
that
selection,
continue pressing the
~
key until you reach the
selection that you want to
use.
NOTE: Heath/Zenith Data Systems operating systems on the
H-8,
H/Z-89, and Z-90 computers do not check parity with the
Terminal. The Terminal ignores parity on all incoming
data.
DUPLEX MODE
Your Z-29 Terminal can communicate in either full or half dup-
lex.
You can change the mode of operation by pressing the
BJ
key.
HANDSHAKING
The Z-29 accommodates two methods of
"handshaking".
In the software handshake mode, your Z-29 Terminal will auto-
matically generate the XON or XOFF codes. XOFF signals
that data transmission from the computer to the Terminal
should cease. XON signals that transmissions can be re-
sumed. The Z-29 Terminal will automatically generate the
XOFF code when its internal buffer is almost full.
The hardware handshake is performed via the RS232 inter-
face in conjunction with the
CTS,
RTS, and DTR lines. The
DTE connector makes use of all three
lines,
while the DCE
connector can utilize the RTS line only.
You can change the mode of handshaking by pressing the
Ii]
key.
