Read device and save to file with cat


I've some problems finding out how to read from the serial port, and add the value to a file. I need time-stamps or/and numbered lines if that possible.

This is what I've made so far.

Code:
cat /dev/ttyS0 < /var/www/ordna/text
Can someone give me a tip how to work it out?

Thanks.

Have you looked at this? http://www.linuxquestions.org/questi...vttys0-494454/

For the timestamp, you can just use cat to add on the date from the 'date' command.

Code:
date | cat - (some_file/device) >> /var/www/ordna/text
