Do you want:
- One end is a terminal, the other end offers login? "agetty
serial" and "minicom"
- TCP/IP over RS-232 serial? Keyword is "PPP".
- TCP/IP over ethernet attached via USB? "usbnet" and treat them
like ethernet adapters.
- Connect an actual hardware terminal like a VT320 to your Linux
box? "agetty serial" again.
- Something else? Describe it.
