X.3 PAD Parameters

This section describes all 22 international X.3 PAD parameters in numerical order, together

with the functions they control. All parameters and their possible values are decimal numbers.

ASCII control characters (ASCII characters 0 through 31) are entered as key sequences, such

as Ctrl-P. A table of ASCII control characters, their keyboard entry sequences, and their

common mnemonic references appear in

X.25 User-Facility Support and Code References on

page 61.

Certain X.3 PAD parameters can be coded as the sum of their listed values. This allows you

to specify several values simultaneously. Parameter 7, for example, which deals with response

to a break signal, has a default value of 21. This is the sum of three of the previous values:

1 (send an interrupt packet), 4 (send an indication of a break), and 16 (discard data). The

X.3 PAD parameters that can be coded this way are parameters 3, 6, 7, 13, and 20.

1:n Escape from data transfer

When you send or receive data, this parameter allows you to escape from Data Transfer mode

(Terminal mode) and enter Command mode. Flow of data from the network is temporarily

suspended.
