Can I use Infra-red to connect my HPC to my notebook/desktop that runs Windows 95? Yes

Yes, check out the IR FAQ . You'll need these Infra-red drivers on your notebook / desktop machine - To download the version 2 Infrared drivers do this on Microsoft's Web Site home page, click the Support icon. Click Knowledge Base, and select Windows 95, at the search prompt, Enter kbfile W95IR.EXE or W95IR.EXE (size: 444416 bytes), click go, the Article that you want is titled "Windows 95 Support for Infrared Data Association Connectivity" scroll down to the section labelled "Instructions for Downloading" and you'll see a link to download the file!

My Thanks to Gary Rohlke who wrote this and has allowed me to use it on my FAQ. Gary is using a IR-equipped Dell Latitude LM notebook PC.

Getting set up.

On the PC:

Enable the IR port in Setup on the PC.

Select Add New Hardware dialog session in Control Panel to install the IR port. Windows 95 recognizes the previously enabled port as new hardware and installs it. I didn't load any special drivers, I let Win 95 install it, so I can't say for sure what driver was actually used.

Then, Start/Programs/Accessories/Direct Cable Connections and click on Install New Ports. This installed a new serial cable connection for COM4, which I think is actually a virtual port for the IR.

Open the Infrared Monitor from Control Panel, select the Options tab and check Enable infrared communication on COM2. Just below this a message reads: "Providing application support on COM4 and LPT3". Everything else is left as the default settings. An icon for the IR monitor should appear in the Taskbar Tray Status Area, and it should indicate the IR port has been enabled.

On the HPC (Gary has a Velo)

To set up an IR connection on the Velo 1 (should work on any WinCE HPC) you can find instructions on Microsoft's WinCE FAQ page. Here's the condensed version (with taps indicated by "\").

Start\Programs\Communications\\Remote Networking\\Make New Connection\\. Enter a name for the connection - I used "PC via IR". Direct Connection\Next\ and select Infrared Port. Finish\.

To select the HPC IR port for communications.

Start\Settings\Communications\\PC Connection\Change, then select PC via IR. OK\OK\.

Starting communications:

Align the IR ports within a foot or so of each other. It will also work bouncing off a nearby reflective surface such as a wall (an airline seat works, too!) if it is close enough. This allowed me to have both units facing me, even though the IR ports were on the back off both units.

Launch HPC Explorer (in my case v1.1) on the PC and select File/Communications. Then select Serial cable on COM4. Click OK.

On the HPC tap PC Link. As soon as the two units recognize each other, the IR Monitor in the Taskbar Tray shows two IR icons facing each other with a simulated IR "signal" between the two icons. You can double click either IR icon to open the IR Monitor and verify the quality of the signal.

Then proceed as usual with HPC Explorer.

I suspect this will work with many IrDA compliant IR interfaces. One may have to get v2.0 of the IrDA driver (available from Microsoft as a download). Fortunately I didn't have to fool with the driver.
