Setserial sets and/or reports the configuration information associated with a serial port. This information includes what I/O port and which IRQ a particular serial port is using.

This version has a completely new approach to configuration, so if you have a setup other than the standard ttyS0 and 1, you will have to get your hands dirty.

By default, only ttyS0-ttyS3 (COM1-4 in DOS/Windows terminology) are configured by the kernel, using IRQ 3 and 4. If you have other serial ports (such as an AST Fourport card), or if you have mapped the IRQs differently (perhaps COM3 and 4 to other IRQs to allow concurrent access with COM1 and 2) then you must have this package.

Options

seserial with -g option help to find out what physical serial ports your Linux box has.

Programs

Once serial ports identified you can configure Linux box using various utilities:

• ["wvdial"] or other GUI dial up networking program - a PPP dialer with built-in intelligence, installed in Ubuntu.
• ["minicom"] -the best friendly serial communication program for controlling modems and connecting to dump devices.
• getty / agetty - agetty opens a tty port, prompts for a login name and invokes the /bin/login command.
• ["grub"] configuration - To configure serial port as the system console.
