Signal Strength and Serving System?

>

I use PPP a lot on various cellular networks. Have you considered
adding support for signal strength (AT+CSQ) and serving system
(AT+CSS) to PPP Genie? The serving system information returns an SID
(see http://www.howardforums.com/archive/topic/273589-1.html) that
would help users figure out if they are roaming or not.

Thanks,

Brian

anyone has any idea about the various signal strength detection methods available??
