The Siemens M55 is a discontinued product, and I doubt that it has ever had
64bit drivers written for it. You are out of luck re using it with a 64bit
OS..

The responsibility for producing drivers rests entirely with the
manufacturer of the product to be connected, so nobody else is going to step
in to take over support for what is a discontinued product..

I'm using a Prolific USB to serial cable to interface with a front door
call box. (A directory of residents in a multiple).
This thing (the call box) isn't exactly new technology, although the
box is brand new. Here's the thing...when I test the connection
everything appears to be fine but when I ask the software, (Tricomm) to
access the database or just communicate with the box I receive "Runtime
error 8020..error reading comm device."

A different laptop (not mine) running windows xp sp3 which actually has
a serial port (I only have USB, hence the converter) connects and
functions just fine.

I downloaded the latest drivers for the converter after emailing the
manufacturer but I receive the same error message.Is the problem most
likely the 64 bit operating system, the converter (QVS.com model
UR-2000M2), a bad serial cable (connected to the converter) or Vista
itself? Any help at all would be greatly appreciated.

The first thing to do is to look in the Device Manager and see what COM port
it's installed itself as, and then check your software to make sure it
matches. The easiest way to test the device is working is by using
HyperTerminal. Trouble is, it's no longer included with Vista and it's no
longer free to download. You can download a 30-day trial from
[url]http://www.hilgraeve.com/hyperterminal.html[/url] which will do for diagnostic
purposes, or a quick Google search for "terminal emulation software" should
find you some free ones (I can't recommend any because I haven't used them).

Anyway, if you have any sort of terminal emulator, set it to use the COM
port that your USB adaptor is installed on, short pins 2 and 3 in the 9-way
connector (long-nosed pliers should do the job, but make sure they don't
also touch any other pins, or the outer edge of the connector) and anything
you type should be echoed back to you. Take the short off and anything you
type should not come up on the screen. If it does you either have Local
Echo enabled in the emulator or there's something wrong.

This is little more than a confidence check but it should help identify
whether you have a faulty adaptor or not. This is only the start - you have
other things to worry about like baud rate, number of data/stop bits, parity
and flow control but let's go one step at a time...

Don't worry though: the nature of the error message means it's most likely
just not finding the device at all, which usually means means wrong COM
port.
