Urgent Computer Help Requested ...

Today, I inherited a peripheral that uses a 9-pin serial/comm port connection. Well, my machine has 2 serial/comm ports, one of which is a 9-pin, and the other is a 15-pin. The first 9-pin is n use, and the 15-pin is open ...

Is there a male DB15 - male DB9 adapter in existence?

Can someone lend a hand?

Free soup awaits you ...

You should be able to get one, if there is a Fry's electronics or a Computer superstore in your area, look there. That's where I got mine.

You sure that's a DB15 serial port? Is it a female or male? I never saw a 15 pin, could it be a game or MIDI port?

I'm going to take a picture of the back of my second system ...

That should be of some assistance ...

Male to male adaptors do exist.
You can find them easily in computer or
electronic conventions. Try your favorite
computer store(s) first.

And then visit the drugstore for the lube.

I'm not sure what DB is, but it's a female serial port. I'm trying to find an adapter that can transfer that into a 9-pin male serial port.

What kind of computer is this? Serial ports are male (pins sticking out), either 9 or 25 pins. Is this some weird variety?

I'll bet it's a Midi port and won't work as a serial port.

Are you sure you didn't take too many painkillers?

It's a joystick port, that has a 15 female adapter. Is that COM2, or?

It is a joystick/midi port, not a serial port. Not COM1, 2, 3, or 4.

The above picture is of a DB25 to DB9 converter. Count the pins.

Counted. So, is the 9-pin serial port COM1, and the 25-pin printer port COM2?

The 9-pin serial port can be a number of different COM ports. It depends on how you configure the BIOS or card (if it's an add-in). The 25-pin FEMALE port is a printer port, LPT1, 2, or 3 (depending on configuration). You cannot make the printer port into a COM port. It's nor serial, it's parallel.

It says this device needs an accessable COM2, 3 or 4 port. If COM1 is already in use, what are my options?

What is this, your programmable inflatable doll?

Take a look for ports with pins sticking out. Do you have only one or two? They can have 9 or 25 pins.

By the way, here are some wiring diagrams. http://personal.vsnl.com/pinout/#5

Thanks for the diagrams. I have 1 9-pin serial port, which I am assuming is COM1. I need 1 more ...

I bought an ISA I/O Card that has 2 16550 serial ports, but it doesn't fit. Looks like I need the other size ...

You mean PCI?

Strange that your computer only has one serial port. Have you checked the manual to see if the motherboard has two serial ports on it and you can hook up a cable to a bracket with another external port?

I do indeed mean PCI ...

Here's that pic, to see if I overlooked something ...

Yup. You got one serial port. At least external to the case. Your modem is acting as another COM port too, but it does not give you a serial interface. That's weird having the joystick port on your modem.

I would suggest looking at the manual though, just in case.

What are you trying to hook up?

A digitizer ...

With no avail ...

So, what's the cheapest way to get another serial port in there?

Only one serial port in the picture. if thats all the ports on your computer you either need an add on board (PCI probably based on the above messages) or a cable inside (if you have a mother board that supports two serial ports - never heard of one that didnt)... What brand/model of pc do you have?
