through PAD, add enough time to compensate for delays
caused by the network.
3 Set line speed for the device:
Set the line speed for the device associated with
filenum
by entering a new line speed, representing characters per
second, as the value of
buffer . Supported speeds are 30,
120, 240, 480, 960, and 1920 characters per second. Input
and output line speeds are the same. If this call is issued
against a device connected through PAD, the terminal
control action is ignored and a meaningless value is
returned.
4 Set echo ON/OFF at terminal:
Enable or disable read data echo to a terminal through the
DTC. Valid values are:
0
Echo off
1
Echo on
This call is not valid if the terminal is operating in binary
or block mode.
5 Set system break response on or off at a terminal:
Enable or disable system response to the entry of a system
BREAK at the terminal. Valid values are:
0
Disable break
1
Enable break
6 Set subsystem break response on or off at a terminal:
Enable or disable system response to the entry of a
subsystem break character at the terminal. Valid values
are:
0
Disable subsystem break
1
Enable subsystem break
If the terminal is connected through PAD, the subsystem
break must be followed by a
RETURN to signal PAD that
data is to be forwarded.
