Save arduino serial on a .txt file

I want to share a little program I’ve just finished writing on gambas that saves the arduino serial on a .txt file. The program is quite slow and needs some changes but for the moment works well. The program is only for linux. (Note:You must be logged to see the download)
I want to use this program to make realtime graphics with Calc using DDE however i don’t know how to setup the automatic refresh of the DDE link any idea?
