Need Help with 486/33 Set-Up for PIC Programming

[Doug Johnson]

Do you know how to configure the jumpers for this type of serial card?
I'm trying to set up an old 486/33 to serve as a microcontroller
programmer. I've removed the serial mouse that was in the port, and
there are no other ports. The modem has been removed also. If I plug
the mouse back in, the mouse works, but otherwise it's like there's no
port available to MPLAB. I'm not familiar with all this IRQ stuff, but
I'm trying. Any suggestions will be appreciated. Picture of the
serial card is at http://mail.chartermi.net/~drjohnson/serial.jpg

Go into the bios and see if the hardware comports are both
enabled. If the computer had an internal modem installed, then
one probably has been disabled to allow the modem to work.

looks like somebody found out the hard way this isn't a binaries
group... ^_^

you need an IO card which has the printer, Serial port and maybe a
game stick port on it.
you may have a VLB , i just happen to have one of those cards here
sticking out of the garbage can getting ready to find its final resting
place.
P.S. they also had the IDE interface socket on most of them too!

Hi Si,

I did not see the OP, so I will respond here. Hope you don't mind.

I can't read the silkscreen on the card, but the jumpers should refer to IRQ and I/O memory location.

The settings should be:

COM1 = IRQ4 & 03F8
COM2 = IRQ3 & 02F8

If you are using Windows, go to System in your Control Panel, and check out Device Manager. Under Ports (COM & LPT), the resouces
tab will tell you what Windows thinks these settings should be.

Hope that helps.

Tim

Looks like somebody doesn't know the difference between posting a
binary to a news group and posting a link to a web page... ;-)
