I'm trying to make my own oscilloscope and I was trying to find out what the best application would be to use to convert data from the serial port to a visible display might be?
I know I could get buy one fairly cheep if I looked in the right place but I just have this stange desire to make one using my PC as the screen.

i'm building a scope at the moment: http://cakenet.dynu.com/scope.jpg what application to convert the data? well you'd have to write your own, presumably in c. that's what i did, and over a parallel port i sample 4 8 bit channels with a hardware buffer running at 20mhz. front end in gtk, using the gtkextra gtkplot widget to make grpahs a synch to draw.

y'know i could send you my schematics for... $80??

that's an interesting question. Have you tried minicom? There might be a minicom mode that might work
