USB/Serial RS232/RS485 Communications

807589Feb 9 2006 — edited Oct 12 2008

I am trying to write (in Windows XP) a program that will access a RS485 device.
I originally started writing the program and used a Serial RS232 -> RS485 converter using the (old version of) javax.comm library.
I now find out that I am going to have to use the software on a computer that does not have a RS232 port.
I have a serial -> RS232 converter, but I was unsure of how to approach changing the code for this situation.

Summary: I need to know how to access a RS485 device through a USB->RS232 and RS232->RS485.
This is my first shot at hardware control, so any ideas would be useful.

Thanks,
Brandy
