I have been experimenting with an RS-232 null modem cable and am curious to know how one would allow FreeBSD to use a serial port as a terminal, like in the days of the PDP-11 where all users had dumb terminals connected to the computer via serial connections. I wish to do the same with a headless FreeBSD machine with a serial cable running to my main PC which is using PuTTY to communicate over the serial port. Before you ask why I don't use SSH for the same purpose, I prefer this type of connection because if the network were to go down I would still be able to log into the server and see what exactly is happening, whereas if the same situation occurred with SSH I would be mostly out of luck, if that makes any sense at all. I have seen other similar questions with answers pointing to
minicom but these seem to be for fulfilling the role of PuTTY on the BSD side, which is not what I want here. What I want is a serial port configured at a specific baud rate with
getty running on it, etc. as if it were an actual terminal.
To answer the question of what version of
init I am running, I am using FreeBSD 10.3, and I haven't changed anything at the system level so it's running the default BSD-style
init that uses rc scripts.
