8 Obtain time used for completion of last read:
Determine the time, in seconds, required for the last read
to complete. Ensure that this call is placed immediately
after the read to be timed, with no subsequent reads in
between. Only read access is allowed for this request. All
reads are timed, so there is no need to enable the timer.
9,11 Set parity generation and checking on or off:
Enable or disable parity generation and checking between
the driver and device. Valid values are:
0
Disable parity; all eight bits of each character are passed
through.
1
Enable parity; type of parity specified by the parity setting
is in effect.
Input and output parity is the same. If issued for a
terminal connected through PAD, CCE (2) is returned, but
no terminal control action occurs.
10, 12 Set type of parity:
If parity is enabled, this request determines what kind of
parity is computed when parity is checked:
0
No parity check on input, eighth bit set to 0 on output
(parity type = zeros)
1
No parity check on input, eighth bit set to 1 on output
(parity type = ones)
2
Even parity checked on input, even parity generated on
output (parity type = even)
3
Odd parity checked on input, odd parity generated on
output (parity type = odd)
If parity is disabled, no parity is used.
If issued for a terminal connected through PAD, CCE (2)is
returned, but no terminal control action occurs.
14 Set line deletion response:
Enables or disables the transmission of line deletion
characters (!!!) to the terminal after a user cancels a line at
