PAD Commands

Sets the X.3 parameter n to value v and displays the current setting of all parameters. This command is a combination of the set and par? commands.

stat

Displays status information of a VC. padem responds with “FREE” if no VC is established or with “ENGAGED” if there is a VC established.

[r,g[n[n]]-] x121_address [subaddress] [P/Dd..d

Performs a virtual call to the remote host defined by its X.121 address. x121_address[subaddress] can be replaced with “symad” where symad is defined in the file /etc/x25/x29hosts. P specifies the packet size negotiation. D specifies the Call User Data (CUD).

Extended Command Set

aprof	Lists all profile IDs known to padem. The profile IDs
	are contained in the x3config file.
help	Displays a complete list of all padem commands with a
	short description of each.

ifname [string]

Displays or sets the programmatic access name of the interface to which padem is (or will be) connected.

	If this command is entered with a programmatic access
	name specified in string, padem sets the
	programmatic access name for the interface. If the
	command is entered and string is not specified, padem
	displays the programmatic access name for the
	interface.
list	Lists all symbolic names for remote hosts that are
	accessible to the user. The symbolic reference names
	are contained in the /etc/x25/x29hosts file.
lprof	Displays the last loaded profile ID.
quit	Terminates padem. If the SVC is still connected, it is
	cleared.
sleep s	Suspends padem for s seconds (maximum 3600).
