Monitoring signal strength with a KPC650 on Linux

Hey all. I've got my KPC650 up and running on Verizon's network from Linux. It all works great, but I need to find a way to monitor signal strength. Anybody know how I can do this? I'm a programmer so if there's no software but you can give me some hints about where the raw data lives I might be able to code something.

Thanks!

I think I read at one point that the mechanism used to monitor signal strength (in Windows) is proprietary (some sort of preemption type of thing)...which is why there is no tool to do it under Linux. I personally haven't verified this or looked for any published docs on the subject. I would think if you could find documentation on how this is done, you could implement it in driver code. ..and you should be fine legally as long as you use it for yourself and do not distribute it.

The KPC650 does operate a proprietary protocol that the connection manager (VZAccess Manager, for example) uses to obtain the signal strength information. There is also a method to extract RSSI values from the card using Qualcomm's diagnostic mode but that is proprietary to Qualcomm and so the information is not publicly available. You may be able to figure it out if you know what you're doing but there isn't going to be any documentation for it.

Packages that may interest you:

comgt
pcmcia-cs
pcmcia-utils
minicom
microcom

comgt is the package you should read up on though the minicom and microcom do have a few goodpoints.
