The system request simulation string specified must be the first 5 characters of data.
It
is not recognized if it occurs in the middle of user data. Mter entering the system
request simulation string, up to 251 characters may be entered. The message is
ended by one of three actions: entering all 251 characters, entering a defined line
turnaround character, or exceeding the text timeout. The 3708 transmits a message
to the SSCP and return back to the application. The 5 characters making up the
system request simulation string are not sent to the host.
Delete Rubout Character
Choices are 1 (Yes) or 0 (No).
If configured, the 3708 deletes rubout characters in the data received from the
downstream device. The rubout character is X'7F' for 7-bit data or X'FF' for
8-bit data.
Delay after Carriage Return
Choices are 000 - 255.
This option applies to hard copy devices, keyboard printers, or printers defined as
keyboard printers. This value defines the number of DEL characters, X' 7F', to be
sent after carriage return (CR) or horizontal tab (HT) to allow the print head to be
repositioned before sending more data.
Notes:
1.
Set to 0 for keyboard displays. If the DEL characters are unacceptable to the
attached device, the 3708 can be set to send either NUL or XON
(X'OO'
or
X'l1'). Refer to Chapter 7, "Nonstandard Operations" for more information.
2. This value is the value used when Delay After Receiving CR is selected.
3. Set to 0 for keyboard displays.
Delay after Form Feed
Choices are 000 - 255.
This option applies to hard copy devices, keyboard printers, or printers defined as
keyboard printers. This value defines the number of DEL characters, X' 7F', to be
sent after form feed (FF) or vertical tab (VT) to allow the print head to be
repositioned before sending more data.
Note: Set to 0 for keyboard displays. If the DEL characters are unacceptable to the
attached device, the 3708 can be set to send either NUL or XON
(X'
00' or X' 11').
