Xport BSOD

[Kyle Soldani]

On a chase in Lexington, MO yesterday I was running Spotter Network, GRLevel3 and Delorme. To split my GPS I use Xport, haven't had any luck with other COM emulation software.

Has anybody encountered the BSOD? "driver irql not less or equal" "xport.sys".

I'm a computer tech, so go ahead and throw tech terms out, I'll catch on. Just wasn't sure if this was a common problem and how to fix it..

Thanks in advance.

Kyle,

"driver irql not less or equal"

Best guess that you have a another com port conflicting with the software Xport.

Both fighting over the same IRQ / port.

do you have any hardware comports? Do you have a modem or bluetooth enabled - what about an Infra Red port (are these still used).

Then there is the software com ports that USB's create.

Have you tried Franson GPSGate? - works well for me

Is this on Windows XP or Vista?

System specs.
Gigabyte 775 Mobo
P4 3.0Ghz
512MB DDR2 800
80GB WD Sata
XP Home SP3

I do have hardware com, but don't use it. No modem, bluetooth or infared. I do however have mobile broadband and wifi, wifi is disabled while chasing though.

It wont be the WiFi - you can rule that out
Try disabling the hardware com port in the bios.

Regedit - HKLM / Hardware / Devicemap / serialcomm

look for clues there.

GOLDEN rule with USB GPS etc - always plug them into the exact same USB port EVERYTIME

Plugging it into another USB will cause it to be allocated a new comport number - this will mess up your port splitting etc.

 

[Kyle Soldani]

Alright, I'll disable the com port.

The PC doesn't move, so the GPS is always on the same port. If it comes down to it, I'll go ahead and get GPSGate, I chased a minor storm in Lexington for this exact reason, to stress test everything. I need a bulletproof setup, and if it costs an extra $40, so be it.

FWIW, I tried xport and had BSODs. I didn't have any similar issues with the trial of GPS Gate.

Ya, I'm using GPS Gate now as well, xport still bsod's for me occasionally.
