ZRECSIZE An integer that specifies the maximum number of bytes
the subdevice can send or receive in a record.
recommended record size depends on the protocol used
and the type of subdevice as follows:
CRT terminal
PTP subdevice
ZXPARENT A Boolean variable that controls transparent-text mode
for the named subdevice.
VAL-TRUE, transparent-text mode is enabled for the
subdevice; if the value is ZSPI-VAL-FALSE, it is not.
The default is ZSPI-VAL-FALSE.
Transparent-text mode can only be enabled if the TR3271
line is configured with the EBCDIC character set and
control set, and transparent-text mode is enabled for
the line.
ZTYPE A pair of integers that specifies the device type
and subtype of the subdevice to be altered.
first integer is the device type, which depends on
the protocol being used.
the subtype, which depends on the terminal being
represented.
