Is it possible to use the serial port that is on the motherboard? I can make my own cable to fit those pins but its not prefferable...

Sure, it's easy.

Make your own cable, it's easy and fun and you'll save some bux.

You're gonna ask me how, and I'm gonna tell you to looka round because I posted details earlier on how to do it and where to get parts cheap.

I have the LK204-25PC and made a cable using ribbon cable from an old floppy cable and solder-less connectors from Radioshack. Plugging that cable in to the built-in COM1 on the mobo works fine. However, in an effort to clean things up a bit I tried plugging the cable in to the COM2 using the mobo header and the connector that came with it.

Any idea why using COM2 gets me no input, only these little boxes that slowly fill the screen. I am sure the cable is good bc it works with COM1, and I have tried another header cable with no change. I do not have any other serial devices to test COM2 with to make sure the port is good, although I may can snag a modem and make sure signal is getting through. Any other ideas would be much appreciated.

Also, I looked around the MO forums and Bit-tech.net forums but may have missed it. I was hoping to find a guide on how to use the USB port to connect this LCD (if possible). If my COM2 is DOA USB may be a good option.

Thx in advance for your help. Oh and by the way, Henry. Its partly bc you took the time to answer an email I sent you that I bought this LCD. I am very impressed by the level of support and quality of the product @ MO. Keep it up, maybe all the other HW vendors in the industry will notice and figure out this is the best way to treat customers.

A lot of mobos have a BIOS setting that allows IrDA to use the COM2 IRQ. You'll want to disable that, it could be stomping on your COM port.

Let's see, for USB -> serial, it typically is as easy as buying a converter for $30-40, then installing the driver, which will give you an additional COM port, say COM3, then configure your favorite software to use COM3. That's why no guide.

Must be something with my mobo, only Com1 works no matter what I try. So I had to lengthen the serial cable to reach outside my case :( . Its not as clean, but it works and I got a lot of positive feedback on my case and the LCD at the last LAN. Thx for the troubleshooting input though, much appreciated.
Since I don't use AMD or Intel I am working on a new Hamster mod. 12v to the treadmill works wonders for overclocking the little buggers.
