There are two features that the Phone Manger appears to
be missing, that I wish it had:
1) Daemon Dialing: Repeated dialing of the same number
until a connection is made.
2) Speaker Toggle: Turn the speaker on and off manually
during a phone call. Useful say, if someone puts you
a lengthy hold after answering the phone.
Both are clearly possible in software, given the phone
ioctls that exist in the software. My guess is that
1) is something AT&T doesn't like, I don't think I've
seen it on an AT&T phone. Probably 2) no one thought of.
Has anyone written a standalone program to do 1)?
As far as 2 it seems like it could be done with an external
program that just opens /dev/ph and issues the ioctl,
except that I expect the phone manager must do an exclusive
open on the device. In fact it may be the case that
the device is inherently exclusive open. Any comments from
someone with experience writing for the device?

Open kept returning errno 16 device busy.
