Remote Host Call Commands

This section describes the commands you use when making calls to a remote host. They are listed in alphabetical order.

break

The break command sends a break signal to the remote host. The effect of the break signal depends on the setting you make using breakaction. By default it sends an interrupt signal and an indication of break to the remote host.

call

The call command makes a call to a remote host. You must enter it followed by at least one parameter--the name or address of the host you want to call. You can also enter other parameters to specify extended addressing and facilities.

The available parameters are:

hostname/alias

This is the hostname or alias configured for this destination by your System Administrator in the PAD Hosts Database. If this is the only parameter you enter, the pad program uses the parameters set in the PAD Hosts Database.

address

If you are making a call across a Packet-Switching Data Network, you must enter the remote host's X.121 address. This is almost certainly a DTE address and can be up to 15 decimal digits long.

If you are making a call to a host on the same LAN as you, you must enter its LSAP address. This is 14 decimal digits long and is made up of the host's 12 digit MAC address, followed by a 2 digit SAP address. The default SAP address for X.25 systems is 7e. For example, if the remote host's MAC address was 080020092186, its LSAP address would be 0800200921867e.

address extensions

You can specify additional components to a numeric address. Each must be preceded by an identifier to tell the software what kind of extension this is. The available components and identifiers are:

facilities

You can use this parameter to override the facilities set by the System Administrator in the PAD Hosts Database, or to set facilities for a call to a host that is not in the PAD Hosts Database. The facilities you can set are:

• incoming and outgoing packet sizes--syntax: pnumber/number

• incoming and outgoing window sizes--syntax: wnumber/number

• fast select--syntax f

• reverse charge--syntax r

To specify a packet size, use powers of two, for example p7/7 means 2 to the power of 7, that is 128 for incoming and outgoing packets. The example below shows setting packet sizes to 256, window sizes to 2, using fast select and reverse charging:

PAD: call address p8/8w2/2fr

Closed User Group

If the host you are calling is a member of a Closed User Group, enter its CUG number. If it is a multi-user CUG, precede the number with a G. If it is a bilateral CUG, precede it with a B.

Network User Identifier

If the remote host is attached to a PSDN that requires you to provide an NUI for security reasons, enter it, preceded by an N.

Recognized Private Operating Agency

You can enter a 4-digit RPOA number to provide additional routing information, if this is relevant to your network. To enter multiple ROPA numbers, enter them as a single string of digits.

clear

The clear command closes the current connection to the host. Some hosts automatically close the connection for you when you log out. In this case you do not need to use the clear command.

hosts

The hosts command displays a list of the hosts in the PAD Hosts Database. These are the hosts you can call by name.

int

The int command sends an interrupt packet to the remote host.

loghost

The loghost command displays the incoming and outgoing X.29 messages between the pad program and the remote host on the screen. You may be asked to use the loghost command and report the output if you contact your support organization with a question.

The loghost display looks like this:

PAD: loghost on
PAD: call host1

quit

The quit command closes the connection to the remote host, exits the pad program and returns you to your local system prompt.

reset

The reset command sends a Reset Request to the currently connected host.

status

The status command tells you whether you are currently in Call or Command Mode and gives the name of the remote host you are connected to.

status all also tells you which parameters apply to this call:

PAD: status all

Break-in sequence is '^Pa'

Echo = ON, Echomask = 192, Flow = ON, Lfinsert = 4, Breakaction = 5
Pagewait = 0, Width = 80, Forward = 126, Timeout = 0, Message Mode
Profile = V5, Vdu, Loghost = ON

Call Status: Call Connected
Host     hostname
PAD: 

width

The width command lets you specify the width, in columns of the terminal or window you are using for this call. The valid range is 20 - 255. The default width is 80. If you enter width without a parameter, the current setting is displayed.
