Interesting...

+CSS: ?, 22

OK

When connecting to the modem (with kermit) echo was off so my command
isn't visible, but it did return the above.  What does the 22 mean or
imply?

I have also noticed these warnings:

May  6 19:12:40 fbx ModemManager[277]: <warn>  Could not get service status: No AT port available to run 
command
May  6 19:13:10 fbx ModemManager[277]: <warn>  Could not get service status: No AT port available to run 
command
May  6 19:13:40 fbx ModemManager[277]: <warn>  Could not get service status: No AT port available to run 
command
May  6 19:14:10 fbx ModemManager[277]: <warn>  Could not get service status: No AT port available to run 
command

And they keep repeating every 30 seconds.

I have encountered this the last time I connected.  The ppp connection
was working fine but this message kept repeating the whole time the
connection was up:

At about 2 per second, the log file quickly becomes pretty huge.

Thanks again for replying.
