[ wants to do phtoggle from cron ]

Well, what you really want to do is tell the phone manager to do it's thing
and switch the lines. Although you COULD switch them with your own ioctl(2)
calls, the phone manager would just switch it back, or crash. What the
phtoggle progam does, is write a command to a file in /usr/lib/ua, then send
a signal to ph, who's pid can be found in another file in /usr/lib/ua. You
could replace phtoggle with your own program, but I don't think that would
solve the window problem, because it is probably coming from the phone manager.

I am being vague about details because I haven't run the phone manger in some
time. I found that I am rarely at the machine when the phone rings, a grep
of a file in my home dir works ok, and I don't want to run a 200k+ program
(ph from the fix disk)
