Solstice X.25 9.2 Administration Guide

X.3 Parameters

The X.3 Parameters window is accessed when you select User-Defined from the PAD Profile window in the PAD Hosts Database, or when you select Customize under PAD Parameters in the PAD Daemon Listen Database.

If none of the seven profiles provided with the product suit your needs, you can modify some or all of the 22 parameters defined in the 1988 CCITT X.3 recommendation. Your network provider should tell you which values you need to set. The parameter numbering is in accordance with the X.3 Parameter standard.

1: Recall Character

Setting this parameter lets you configure a character to use to switch from the data transfer state to recall the PAD. Table 7-7 lists the possible values.

Table 7-7 Recall character values

Decimal Value 

Character Used 

0 

none 

1 

DLE (Ctrl-P) 

32 - 126 

user defined character 

Note -

Decimal values 2 to 31 (inclusive) have no effect.

2: Echo

If this is set to On, the PAD echoes characters back to the terminal, in addition to processing them.

3: Dataforwarding

The Dataforwarding characters tell the PAD that it has received a complete packet sequence, which it should assemble and forward. Possible values are:

If your PSDN has supplied you with a numerical value, you need to find out which character sequence it defines.

4: Forwarding Delay

Determines the interval PAD waits for after receiving at character. If no character is received by the end of this interval, the PAD assumes it has received a whole packet, and forwards it.

5: Flow Control by PAD

Determines the type of flow control used by the PAD on incoming data from the terminal. Make sure that this is the same type as is used by the terminal.

6: Service Signals

Set the decimal value according to the way you want PAD service signals to be handled. Table 7-8 lists the values and possible actions.

Table 7-8 PAD service signals

Decimal Value 

Action 

0 

no service signals transmitted to start-stop mode DTE 

1 

service signals, other than the Prompt PAD service signal, are transmitted in standard format 

4 

prompt PAD service signal transmitted in standard format 

8 - 15 

PAD service signals transmitted in a network-dependent format 

7: Action on BREAK

Determines the action taken when the PAD receives a break signal. Choose from the list of available options. If your PSDN has supplied you with a numerical value, you need to find out which break action it represents.

8: Data Delivery

Choose the value you want.

9: Padding after <CR>

This lets you set the PAD to insert padding characters in the character stream after the occurrence of a carriage return. This lets the terminal process the carriage return correctly.

10: Line Folding

Determines how often the PAD inserts a Line Feed followed by a Carriage Return. In effect, this sets the line length for your terminal.

11: Binary Speed

This displays the speed of the line connecting the PAD and the terminal. You cannot change this parameter.

12: Flow Control by Terminal

Defines the type of flow control used by the terminal on incoming data from the PAD.

13: <LF> Insertion

Determines when the PAD will insert a Line Feed character. This is only relevant when the PAD is in data transfer state. If your PSDN has supplied you with a numerical value, you need to find out which action it represents.

14: Padding after <LF>

This lets you set the PAD to insert padding characters in the character stream after the occurrence of a line feed. This lets the terminal process the carriage returns correctly.

15: Editing

This provides for local editing during the data transfer state as well as during the command state.

16:Character Delete

This determines the ASCII character used as the Character Delete key. Enter the appropriate ASCII number.

17: Line Delete

This determines the ASCII character used as the Line Delete key. Enter the appropriate ASCII number.

18: Line Display

This determines the ASCII character used to redisplay a line. Enter the appropriate ASCII number.

19: Terminal Type

Specify whether you are using a video or hardcopy terminal. This affects how the PAD handles deletions.

20: Echo Mask

Choose the appropriate echo mask. Possible values are:

If your PSDN has supplied you with a numerical value, you need to find out which mask it represents.

21: Parity

Set the parity to None, Checked, Generated, or Checked and generated.

22: Page Wait

The PAD halts the display after the number of lines you specify here. Pressing the space bar displays the next page of data.
