I can't seem to talk to it at all. Shouldn't I get an "OK" when I send
"AT"? I get nothing. Sorry, it's been a while since I used a modem
interface.

Also, noticed this in syslog when I stopped ModemManager:

[ 9714.958568] traps: ModemManager[934] general protection
ip:7f97d934ca75 sp:7ffe58e0d7e8 error:0 in
libglib-2.0.so.0.4800.2[7f97d92be000+10f000]

Thanks for your help,

A.
