Getting data from an RS-232 port

What is the best way to do this:
1) Request measurement data from a scientific device connected to PC with RS-232 cable. (On Windows XP box)
2) Receive data
3) Display data in an app for a user to add comments and input other measurements that are not sent down the RS-232 cable
4) Send data to database

I can do 3) and 4) (I think) but I don't know about getting data from the serial port.

Will someone give me advice?
Any help appreciated,
Karen

PS Bonus question:
I want to do the app in RoR but time-conscious collegues are strongly suggesting I do it in Java. I understand that the support for the "way" to do it in Java has been withdrawn for Windows, so whichever way we do it we may have to have a C program talking to the device. Is this correct? Any comments on RoR vs Java for this?
  
Hi Karen,

The way to do this is to have a client program that runs on Windows and POSTs the data to the website. Steps (1) and (2) will typically involve the implementation of a piece of software that meets your protocol requirements and can receive data from it.

This is *exactly* what I have just done for a client. Would you like to contact me off list?

Cheers
Mohit.

Hi Mohit,
That would be good - how do I do that? I post these messages via ruby-forum.com and I can't see an email address for you!
