Minicom and SLIP
I was trying to establish a SLIP connection with a stupid managed switch that claimed it talks SLIP in the docs. It doesn't - it talks serial just like everything else with a serial console port. But that was hard to discover because using slattach to try to establish a slip connection seemed to render my serial port useless. I imagine you could reset it somehow with setserial, but I'm easily confused by serial stuff so I just rebooted. Store that away in your databanks: using minicom after slattach (even if you rmmod slip and all that good stuff) doesn't work without voodoo or reboot.
