The profile number used by the PAD is the decimal value of the binary number
calculated from Table 4-3 "PAD Profile
Field" as done by the [Compute Byte] function key. An "x" in a box
means that the value doesn't matter: that is, the values of the bits are not
dependent on each other. Bit 7 is reserved for future use, and is set to 0.
Note that you can only use certain combinations: meaningless or dangerous
combinations are blocked and cannot be entered.
Terminal with init profile set; Bit 0 is 1 = 1
Data forwarding 3:127 4:0; Bit 1 is 1 = 4
X.3 setting allowed; Bit 4 is 0 = 0
No PAD test during connection initialization; Bit 5 is 1 = 32
Profile number = 37

PAD Profiles and Access Password
When users attempt to establish a connection from a PAD, the PAD selection
command may specify a password and/or a profile number. The password will be
needed if a password has been configured for the DTC that contains the X.25
card being called. The profile number may be specified to override the PAD
profile field configured for the PAD port.
The password is configured on the DTC Configuration screen in Step 6: Specify
DTC Configuration. Refer to Chapter 3 "Configuring DTCs
Step-by-Step" for information on configuring the password.
The PAD profile number is the number displayed by the [Compute Byte]
function key. The section DTC PAD Profiles contains a list of PAD profiles
that are available. Entering a profile number in the PAD selection command
causes the DTC to use the particular PAD profile when the connection is
established.
The syntax to enter a password and/or profile number for the PAD selection
command is:
@<X.25 address>,d[<password>][/<profile number>]
The following example supplies the password "secret" and causes the PAD
profile 33 to be used.
@ 1234567891234,dsecret/33
Forced Data Forwarding
When a connection is established to a PAD device, two of the characteristics
that get set, are the data forwarding parameters. The data forwarding
parameters tell the PAD when a packet must be sent to the PDN. The behavior of
data forwarding is set with the fields "Data forwarding parm #3 and #4" and
"Forced data forwarding" on the PAD Terminal Profile screen. The Forced data
forwarding field also affects how the "Data forwarding parm #3 and #4" field
behaves. See the PAD Installation manual for further information on the PAD
parameters.
On the PAD, Parm #3 selects the set of characters that will signal the PAD to
forward data to the PDN. Parm #4 sets the idle timer in 1/20 second increments.
The idle timer will signal the PAD to forward data if the time between
successive characters from the terminal exceeds the idle timer value.
When "Forced data forwarding" bit is 0, the "Data forwarding parm #3 and #4"
behave as described in the
Configuring Systems for Terminals, Printers, and Other Serial
Devices manual. The value specified in the field will be used
when the connection to the is in:
VPLUS mode;
Telnet mode;
character mode when EOR and AEOR are not carriage return.
The value in the field is not used during a connection when in character mode
and EOR or AEOR is carriage return. In this case the default values will be
used: parm #3 is 2 and parm #4 is 0.
When the "Forced data forwarding" bit is 1, the data forwarding parms #3 and
#4, that are set at connection time in the PAD, are ALWAYS used.
