13 PAD Test
Init profile
X.3 setting
Data forward 4:2
Used in data transfer.
Recommended for more performance in iX for
VPLUS mode (NS/PAD compatibility) or for
character mode applications which need to send few
characters to the host.
The profile loads the X.25 line with many, small
packets each time the application requires a
termination character other than CR.
The PAD must support 4:2.
17 PAD Test
Init profile
No X.3 setting
Data forward default
Used in data transfer.
Recommended if you don’t want to change the
hardcoded initial profile set by PAD Support when
an application controls requires the setting of X.3
parameters other than echo, break or flow control.
The user must ensure that the editing characters
are <BS> (ASCII 8) for backspace, and Control-X
(ASCII24) for the line delete character.
33 No PAD test
Init profile
X.3 setting
Data forward default
Used at connection initialization.
Recommended for more performance at the
connection initialization, or if the PAD doesn’t
support the setting of multiple Set and Read, or
isn’t able to answer during the “PAD Test” sequence
in accordance with X.29 recommendations. For
example, for a PAD which answers with an X.29
PAD error at a parameter setting instead of setting
the “error bit”.
The PAD must support the X.3 setting needed by
the applications.
35 No PAD test
No init profile
X.3 setting
Data forward default
Used at connection establishment.
Recommended if the user wants to keep the profile
set before connection initialization.

the applications.
