Serial Ports

by Lodge1429 / December 20, 2008 11:36 PM PST

Hi, I'm playing with a reconstructed computer with the intention of using it for Ham Radio appliations.
I have installed XP pro and broadband and, so far, all is well. I am using it right now !
However, the computer only has a games port (15 pin) and LTP printer port.
According to the system analysis, it has a coms port - on the usual address.
Q Where is this comps port physically fitted ? I haven't taken the side cover off yet - but surely it's not just on the motherboard !
Help appreciated.
Dave

I read your post 2 times and can't find the make and model of what we are dealing with. Serial ports appear on the rear of some motherboards. Some are just headers on this or another board. But given the details so far all I can offer is that you tell more or just open it up.

Hi Bob
Thanks for your comments.

Difficult to give a description of the beast, but here goes :-

Tower
Running XP (SP3) (original software as far as I know)
Bios American Megatrends - release 07/22/2004 K7S41 bIOS P1.60 ACPI compliant BIOS
AMD Durin 800 Mhz (100 * Cool CPUID : 0631
----------
Tower has a 15 pin & 25 Pin "D" connectors (Game /printer ports ?)
4USB sockets on rear panel and 2 on front panel
DVD writer
----------
Internal
small compact motherboard - no addirional boards or sockets (other than test sockets)

I've run my amateur radio programme (which sets up the external port) and I am then unable to run Hyperlink.
If I run Hyperlink first, I am unable to run my ham software - in both cases being told the port is in use.

What voltages appear on the "games" port - can I assume that it is a "serial" port - or more like a printer parallel port.
What are the in/out and 0 pins on the games port ?
More help would be appreciated (sorry I can't provide more detailed information)
Dave

Many thanks to all and all the very best to you and yours for the festive season.

Amateur radio on computers? How does that work?

"Packet Radio."

Ham Radio on computer - numerous answers.

You may have heard of X25 - communication protocol. This has been adapted (into AX25) by an American amateur and thus allows text communication between two amateurs. The text is converted to ASCII, sent by two tones (like teleprinter [RTTY]) on amateur radio frequencies. The data may be directed to a specific callsign or everyone. If sent to everyone, the data is kept on a Bulletin Board for all to view. It therefore becomes am "Amateur Radio Internet".

Another application sends positional data from a GPS via amateur radio frequencies to other amateurs and allows a moving display of a vehicles position.

Pictures, scanned into a binary form can be transmitted in a similar way.

Hope that helps ...

All you need is the 3 wires for packet radio hookup. Why not make your own?

In my high school day, I player with ham radio but that's about 50 years ago. Maybe I should look into this a little more to see how things have changed.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
