Other times it has rung more than two times and still not executed the
program.  It still always ends with the same messages:

mdm_read_byte: read returned -1: Interrupted system call
wfr: timeout waiting for RING
 wfr: rc=-1 drn=0
phone stopped ringing (rings=2)

... when looking through my log file, I've gotten up to 5 rings and the
program never gets executed.  About the hanging up issue, I have no
idea, it seems to be random.
