How To Fix setserial: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu setserial is provided by setserial package.

setserial is:

Set and/or report 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 COM1-4 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.

To fix this problem, we can install more using the command below.

sudo apt-get -y install setserial

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install setserial.

sudo apt -y install setserial

Or if you have aptitude installed you can use the following command.

sudo aptitude install setserial
