Quoting Character Mode Option
When the Quoting Character Mode option is enabled, the editing characters (backspace and line
delete) and a specific single text terminator are able to be treated literally by preceding them with
the backslash
(/1\").
For example, if you type
\ DEL
DEL is put in the user's read buffer, and the line would not be deleted.
You would be able to
erase the /lDEL" character as any other character typed, even though the echoing of such an erasure
may not look right onthe terminal.
If
followed by any other character, the quoting character causes no special action and is placed in the
text buffer as is any other character.
The quoting character and the specific single text terminator are programmable and have a default
value of the backslash (\) character.
Conditional Output Separators Appendage
When the Conditional Output Separators Appendage option is enabled, the firmware will ex-
amine every outgoing character for the user-specified record separator, which has a default value of
the linefeed character.
If
the user-supplied record separator is found, the firmware sends the output
separators in place of the record separator.
If
the Automatic Output Separators Appendage option is enabled, the output separators are also
added to the end of each message.
Speed Sense Mode
The Speed Sense mode, initiated by Control Card (CC) Subfunction 6, puts the card in a mode where
the baud rate of incoming data is sensed and the channel configured accordingly. The firmware waits
for a "start bit" and, in synchronous mode, samples the incoming data stream at 19200 baud. The
resulting data is compared to known configurations of the 7-bit "carriage return" character (OD
hex). If a match is discovered, the channel is configured for that baud rate, and an event is
generated to inform the host of the baud rate and the state of the parity bit (the sense of bit posi-
tion 8). Searching continues until a match is found, or until the Speed Sense mode is disabled by CC
SF 7.
