Description

When i flashed something over ther serial cable connection in the past, i used screen. But screen is getting old and there's now a tool for that called minicom. Now i am not that wellversed in using it.

But i thought it would be nice to have a integration testsuite for minicom which let's me run this like in the real world.

So, for fun'n'giggles o i thought about writing a kernel module or a bpf program which emulates a serial TTY so i can configure the kernel module live and run minicom and see if everything works like it should.

And as long it works with something which appears to minicom as a valid serial tty connection i am open for solutions.

Goals

• getting more acustomed to minicom
• trying to build something which appears in userspace as a valid tty connection like /dev/ttyUSB0 for example
• having a small testsuite which set environment, runs minicom tests and does proper teardown
