Above you say for some reason and now you say cable was disconnected.
If it is a straight forward RS232 on the mainboard of the server and you are
using something like minicom, you just need to reconnect to the device
(after attaching the cable).
If you have an issue with that, you need to debug what is going on.
IF you have the rs232 serial as module, you can try SSH to the server and
rmmod/insmod or modprobe ... but if you could SSH why would you RS232 to
the server?
Anyway ... based on the scare information, this is the only thing that came
into my mind.
