I've got a system that has an RF device attached to ttyS1 which up until now has been used for telemetry.
So far, over this RF link I can request files, send files, extract system performance info and force a reboot.
To make the system more versatile I'd like to log on over this RF link. Security is not an issue.
The problem is, I don't understand how I can do it. If I do something like getty where getty gets replaced by the login process, then I'm going to loose the code that handles the packetised RF link.
Am I going to have to make my packetised RF link a device driver or are there other ways around this problem ?
