character will control the BNS sessions. The UMI supports attention character sequences that are
printable text, a DELETE, or a single Break. The double break attention sequence is not
supported.

The

crypt=<on|off> option allows an IP session to be encrypted between peer entities. Both

ends of the connection must have encryption enabled or disabled. The UMI uses a dynamic
random key method of data encryption when this option is enabled.

5.23 VIRTUAL PAD ADMINISTRATION

This command configures the virtual pad options of a vport. The options are only relevant when
the vport has been set to

prot=vpad on the vport command.

The

[cnt=<#>]

parameter allows more than one port to be affected. All virtual ports may be

configured with a single command having a

cnt of 504.

The

padecho=< ON | OFF >

refers to reference #2 in the X.3 parameter list. When set to

OFF,

the PAD will not echo characters back to the IP endpoint. When set to the value of

ON, all

characters are to be echoed back to the IP source.

The

paderase=< NONE | BS | <HEX BYTE> >

option specifies reference #16 in the X.3

parameter list. It is used with manual telnet connections to an X.25 VC. It sets the buffer editing
“erase” character. When the special “erase” character is received by the PAD for a specific virtual
circuit, the previous character in the packet accumulation buffer is deleted. If the

padecho

option

was also enabled, a “Backspace Blank Backspace” 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.

The

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
