[Freeswitch-users] USB GSM Dongle with FreeSwitch for voice calls

[Sergey Safarov]

I thinking following device cannot be removed
/dev/ttyU3.3
/dev/ttyU3.3.init
/dev/ttyU3.3.lock
It is exist because GSM device exist (/dev/ttyU3.3) in the system and must
be controlled (restarted, reinited, disabled, /dev/ttyU3.3.init) and device
is opened (/dev/ttyU3.3.lock)
