Hi Steve,
Thanks for help, but ModemManager doesn't seem to be an issue. Question: Does
"Cannot open serial device /dev/ttyUSB0" error mean that
it is unable to connect to my USB adapter or that there might not be a phone connected on
the other end of the adapter?

What is it that I am doing wrong?
If you're using a recent version of Ubuntu/Debian, modem-manager opens
serial devices when connected and probes for a modem.
Also, on older versions of Ubuntu brltty might block the port.
To work around the modem-manager issue either uninstall it, or put a
udev blacklist rule in place (where you insert the VID/PID of your
adapter):
