semicolon will forward any accumulated data including the semicolon. A value of
EXCL indicates
that an exclamation point will forward any accumulated data including the exclamation point. A
value of
ALL indicates that all data is to be forwarded immediately. The ALL option has the effect
of generating single user character X.25 packets on this virtual circuit. The
GRPx values specify
selected groups of forwarding characters.
GRP1 forwards on ESC, BEL, ENQ, and NAK. GRP2
forwards on DEL, CAN, DC2.
GRP3 forwards on ETX, EOT. GRP4 forwards on HT, LF, VT, and
FF. Multiple forwarding conditions are allowed simultaneously. Setting
padfwd
to a value
aggregates with the previous value of
padfwd
. The
padfwd=none
is required to clear the
forwarding conditions.
The
padidle=<#X.3 ticks>
parameter refers to reference #4 of the X.3 parameter list. This is the
time forwarding condition. When it expires, it will forward any data collected to the X.25 circuit.
The timer is reset to the specified timer value whenever a forwarding condition is reached. The
value is based on ticks of 1/20
th
of a second each per the X.3 specification.
The
padparity=< TRANS | EVEN | ODD >
parameter is not present in the X.3 parameter list. It
allows special parity treatment for interface to network elements that require parity. The default
value is transparent operation. The value of
TRANS sets the operation to be transparent. When
the parity treatment is transparent, the data is not modified in either direction. The value of
EVEN
sets the operation to be even parity towards the (B)X.25 device, and stripped parity towards the
TELNET. The value of
ODD sets the operation to be odd parity towards the (B)X.25 device, and
stripped parity towards the TELNET.
The
padcrlf=<NONE | RMT | VC | BOTH
>
parameter refers to reference #13 of the X.3
parameter list. This is the action to be taken when a CR is received in the data stream from the
remote IP endpoint. A value of
NONE indicates that there is to be no LF (line feed) insertion. A
value of
RMT will insert an LF following a CR whenever it is sent towards the remote IP endpoint.
A value of
VC will insert an LF following a CR whenever it is sent towards the X.25 virtual circuit.
A value of
BOTH will insert an LF following a CR in either direction.
The
padcmap=< ON | OFF >
option provides the automatic case mapping from lower case to
upper case. When the option is set to
ON, all lower case characters are automatically converted
to upper case. When
OFF, no transformations are performed.
The
padapi=< TELNET | RAW >
option provides a means of selecting the PAD virtual circuit to
use
raw protocol. The raw protocol is essentially asynchronous, but without the benefit of Telnet
RFC encapsulation. It is used for applications that do not implement the Telnet RFC. The default
for this option is to use the Telnet encapsulation.
