I currently have a Java Applet running on my web page that communicates to a display pole via COM1. However since the Java update I can no longer run self-signed Java Applets and I figure it would just be easier to send an AJAX request back to the server and have the server send a response to a TCP port on the computer...the computer would need a TCP > COM virtual adapter. How do I install a virtual adapter to go from a TCP port to COM1?

I've looked into com0com and that is just confusing as hell to me, and I don't see how to connect any ports to COM1. I've tried tcp2com but it doesn't seem to install the service in Windows 7 x64. I've tried com2tcp and the interface seems like it WOULD work (I haven't tested), but I don't want an app running on the desktop...it needs to be a service that runs in the background.

So to summarize how it would work:

Web page on comp1 sends AJAX request to server
Server sends text response to comp1 on port 999
comp1 has virtual COM port listening on port 999, sends data to COM1
pole displays data

Windows 7 on a 64-bit computer

I read on Wikipedia that Windows 7 on a 64-bit PC needs twice as much RAM as on a 32-bit PC. I understand why is that: every number stored in memory takes 8 bytes rather than just 4. That, in simple terms, means that your amount of RAM is reduced to half when you use Windows 7 on a 64-bit computer… >>> More
