SUMMARY
=======
This article describes the X.3 Packet Assembler/Disassembler (PAD) parameters
that are used in conjunction with PAD.INF for Remote Access Service. PAD is used
to convert protocol to and from a packet-switched network.
MORE INFORMATION
================
There are 22 standard PAD parameters. Parameters 16, 17, 18, and 19 describe the
available editing functions.
NOTE on style: 1:126 = the first parameter (1) and its value (126)
Parameter 1: PAD recall
Description: This enables an escape from the PAD on-line state to the PAD command
state on receipt of a specific character. When the PAD receives this character,
the PAD prompt is displayed on the your terminal monitor.
Parameter 2: Echo
Description: This parameter is set to "0" (zero) for echo and "1" for non-echo.
One of the most frequently used parameters, this is handy for applications used
for suppression of text when you are typing in your name and password. When this
parameter is set, all characters received from the terminal are echoed,
excluding those specified by parameters 5,12,20,22. Setting parameters 12 or 22
to non-zero values suppresses character echo (XON and OFF) even if parameter 2
is set to echo on.
Parameter 3: Data Forwarding Signal (characters)
Description: This value is bit-mapped. The PAD does not usually transmit one
character at a time; it prefers large blocks of data, such as lines of text. A
normal character used for this parameter is [carriage return = 2]. A PAD
manufacturer's manual should have a table showing the options for this
parameter.
Parameter 4: Idle Time Delay
Description: With the Data Forwarding, this parameter provides the capability to
forward data to a host based on idle time. If there is data in the buffer and
there has been no additional characters received in the IDLE TIME, the buffer is
sent to the host. The time units are in 0.05 seconds and the values range from 1
- 255.
Parameter 5: Flow Control - PAD to Terminal
Description: This parameter tells the PAD to transmit the XON/OFF characters to
the DTE, depending on the buffer state.
Parameter 6: PAD Result Code Control
Description: This controls how the PAD result codes are transmitted to the
terminal. The parameter can stop the PAD from sending service codes back to the
terminal in response to events as the X.25 calls for clear or reset.
Parameter 7: Action on Receipt of Break from Character Terminal
Description: This parameter is bit-mapped. The break action here is a sequence
(from the host that the PAD is connected to) for indicating that attention is
required. This can be used in the interruption of a long transmission that the
host may think is hung in a loop or stuck in constant transmit mode.
Parameter 8: Discard Output
Description: Set this parameter so that you can abort a running process on the
remote system by pressing a [break] key. If set to zero [0], normal data
delivery is used.
Parameter 9: Padding after Carriage Return
Description: Specifies the number of {NUL} characters to transmit after a
carriage return.
Parameter 10: Line Folding
Description: This allows for the formatting of data into regular line lengths
when delivered to the character terminal. If a line length is specified, a
[carriage return / line feed] must be transmitted.
Parameter 11: Terminal Speed
Description: This is a READ ONLY value. The parameter shows the current DTE
speed. It is automatically set by the PAD using the last AT command.
Value Baud Rate
----- ---------
0 110
2 300
3 1200
4 600
5 75
12 2400
13 4800
14 7200 or 9600
15 14400 or 19200
16 38400
Parameter 12: Flow Control of the PAD by Local Terminal
Description: This is basically the opposite of parameter 5: it allows the
character terminal to control the flow control.
Parameter 13: Line Feed Insertion after Carriage Return
Description: This specifies whether the PAD inserts a line feed character after
carriage returns. This applies only in the PAD on-line state.
Parameter 14: Padding after Line Feed
Description: This is the same as parameter 9 except that the padding {NUL}
characters instead of a carriage return are inserted after a line feed.
Parameter 15: Editing
Description: This specifies whether editing is used in the PAD on-line state.
Parameters 16, 17, 18, and 19 help describe the available editing functions.
If editing is enabled, parameter 4 (Idle Time Delay) is ignored.
Parameter 16: Character Delete
Description: This defines the delete character to delete the last character in
the editing buffer. ASCII 8 is the backspace character.
Parameter 17: Line (buffer) Delete
Description: This defines the line delete character. ASCII 24 is <Ctrl-X>.
Parameter 18: Line Display
Description: This defines the line display. If you enter the character specified
and editing is enabled, the editing buffer is displayed. ASCII 18 is
<Ctrl-R>.
Parameter 19: Editing PAD Result Codes
Description: This defines the effect of editing buffered characters with the
character delete and line delete functions.
Parameter 20: Echo Mask
Description: Bit-Masked Parameter. If parameter 2 is set to 1, this parameter
lets you select the characters that are echoed.
Parameter 21: Parity Treatment
Description: This controls the parity and character format used by the terminal.
Best left in the "OFF" condition.
Parameter 22: Page Wait
Description: This allows for pagination of data sent to the terminal. If the
terminal display can display 20 lines and this parameter is set to 20, the PAD
sends 20 lines of data then stops transmission.
