HP 48SX Connectivity?

I use a program called HPComm on my Win7 laptop, available here. I've linked to the version I use with the 48sx. I no longer remember why, but I couldn't use the newer version of the program. While the interface of version 2.4 is dated, it is at least still functional on my system.

The biggest issue I'm aware of with this version of HPComm is that it appears to only support COM ports 1-4. This works OK for me, as I have a real serial port on my laptop's docking station that shows up as COM1. The USB/serial adapter I have shows up as COM9, so it's not accessible from HPComm with my setup.

Edit addition: the USB/serial adapter can be reassigned to an unused port in the 1-4 range (I just tried it with COM2). This allowed HPComm to communicate successfully through that adapter in addition to the existing serial port.

There's probably other solutions as well, this is just the particular setup I use to communicate with the 48sx.
