Command Definitions (FCONTROL - FLOCK)
FDEVICECONTROL
a terminal:
0
Disable transmission
1
Enable transmission
Line deletion characters are not output by PAD devices. If
issued to a terminal connected through PAD, CCE (2) is
returned, but no terminal control action occurs.
15 Set transparent editing mode:
Enables or disables transparent (unedited) mode. When
enabled, allows most special characters to be read and
treated as data and a small subset to retain their
meaning:
Enable transparent editing by passing non-NUL
characters for the subsystem break and EOR characters in
the buffer in the following format:
AEOR The AEOR character defined through a previous call to
FCONTROL
itemnum =25. The read terminates in error, and
a call to FCHECK returns an error code of 31. The AEOR
character is passed with the data and included in the byte
count.
BREAK Causes a system break (when enabled) and transfers
control to the system. If the RESUME command is entered,
transparent editing is resumed.
CTRLQ (DC1 or XON) The resume output character of the XON/XOFF
handshake. This character is stripped from the input data
when XON/XOFF protocol is enabled.
DC2 When input as the first character, it is stripped out. A DC1
(
CTRLQ) is written to the terminal. If not input as the first
character, DC2 is a data character.
CTRLS (DC3 or XOFF) The stop output character of the XON/XOFF
handshake. This character is stripped from the input data
when XON/XOFF protocol is enabled.
bits (0:8) Specifies the character to be used as the subsystem break
character. Any character not defined as a special character
in transparent mode (including the standard subsystem
break character) can be used. If set to 0, subsystem break
is disabled.
bits (8:8) Specifies the character to be used as the line termination
character (EOR). Any character not defined as a special
character in transparent mode can be used.
If used for a device connected through PAD, data is not forwarded from the
