6.2 Connection with a single leased link - dial on demand

connection is recovered automatically.

•

If the connection is set to be hung-up at the moment of the outage, the con-

nection will not be recovered.

•

In mode of on-demand dial (i.e. outside the intervals defined), connection

will be recovered in response to the first request (i.e. packet sent from the

local network to the Internet).

Automatic hangup when idle

Dial-ups are usually charged by connection time. When no data are transferred via the

connection, there is no reason to keep the link up. Therefore, it is possible to set also

idleness time after which the link will be hung-up automatically.

For optimal idleness timeout length, it is necessary to know how the Internet connection

is charged in the particular case. If the idleness timeout is too short, it may result in too

frequent hanging up and dialing of the link which might be very uncomfortable and in

certain cases even increase connection costs.

Note: In the time interval where persistent connection of the link is set (see above), the

idleness timeout is ignored.

Dialing scripts

In some cases there is a special need of running a program or a script (execute a batch

command) along with dialing or hanging up a link. This can be helpful for example if

a special type of modem is used that must be controlled by a special program provided

by its developers.

WinRoute allows launching any program or a command in the following situations: Before

dial, After dial, Before hang-up or/and After hang-up.

Note: In case of the Before dial and Before hang-up options, the system does not wait for

its completion after startup of the program.

Dial-up — external commands

Path to the executable file must be complete. If the path includes spaces it must be

closed into quotes, otherwise the part after a space will be considered as a parameter(s)

of a batch file. If the path to the file is quoted, the text which follows the closing quote

mark is also considered as batch file parameter(s).
