tunelp

The tunelp command in Linux is used to control the parameters of the parallel port. The parallel port is a legacy interface that was used to connect printers and other peripherals to computers.

The tunelp command is used as follows:

tunelp [options] [device]

• options: These are optional flags that can be used to control the behavior of the tunelp command.

• device: This is the name of the parallel port. The default device is lp0.

The tunelp command has a number of options that can be used to control the parameters of the parallel port. Some of the most commonly used tunelp options are:

• -i: This option specifies the IRQ number for the parallel port.

• -m: This option specifies the mode for the parallel port. The default mode is SPP (standard parallel port).

• -s: This option specifies the speed of the parallel port. The default speed is 19200 bps.

For example, the following command will set the IRQ number for the parallel port to 7, the mode to EPP (enhanced parallel port), and the speed to 115200 bps:

tunelp -i 7 -m EPP -s 115200

The tunelp command is a valuable tool for system administrators who need to configure the parallel port. It can also be used by users who want to improve the performance of their printers or other peripherals.

However, please note that the parallel port is a legacy interface that is becoming increasingly obsolete. Most modern printers and peripherals connect to computers using USB or other newer interfaces. As a result, the tunelp command may not be necessary for many users.
