I have a toshiba phone system that has a feature where it spits raw data and i can direct that data to a serial port on the toshiba phone system or to an IP/PORT

the data is just ascii data - tells me calls that are made/time/etc

I would like to setup an existing linux box to capture this data and store the data for me

then later i can build reports based on that data (and for me a report could be just a few cat's/greps/etc so basic stuff) - but i can figure this out later.

for now i would just like to GRAB the data on a port and dump it into a file (and recycle files every 24 hours)

are there any built in utilities that can help me do this?

I believe i can use nc/netcat to grab the data - am i on the right track for now?

however not sure about saving files/going to a new file after 24 hr..

A lot of terminal apps can save to files too.

Most time is a cron task. If you stop the app then restart it a new file ought to be created. Might have to edit it to count up.
