sequence is emitted to the user. When the paderase option is set to NONE, the PAD will
not have a special “erase” character. When the value is BS, it is set to the ASCII
backspace character 0x08. Otherwise, any character may be entered as a hexadecimal
byte in 0xXX notation. This option is only valid on X.25 virtual circuits configured with the
PAD interface.
The
padfwd=<NONE | CR | CRDROP | SEMI | ALL | GRPx> option specifies reference
#3 of the X.3 parameter list. This is the forwarding condition (outside the PAD timer)
which will forward data towards the X.25 virtual circuit. A value of NONE indicates that
there are no character forwarding conditions. A value of CR indicates that a carriage
return will forward any accumulated data (including the carriage return). A value of
CRDROP indicates that a carriage return will forward any accumulated data (but not
including the carriage return). A value of SEMI indicates that a semicolon will forward
any accumulated data including the semicolon. 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
padbreak=< NONE | INTR | RESET | BRKIND > parameter refers to reference #7
of the X.3 parameter list. This is the action to be taken when a break indication ( a
standard Telnet encapsulated value ) is received from the remote IP endpoint. A value of
NONE will ignore the break, and it is deleted from the data stream. The value of INTR
will generate an X.25 interrupt packet. The value of RESET will generate an X.25 virtual
circuit . The value of BRKIND will generate an X.29 “indication of break” message on the
X.25 virtual circuit.
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
