Unix-PC phone driver help

[Mike Hudson]

I have a question for all Unix-PC phone driver gurus.
I would like to be able to use the "touch-tones" from the
keyboard after a call has been dialed and connected.
Regular "touch-tone" phones make the number tones at
any time during a call.  I would like to emulate this with
the Unix-PC, but cannot figure out how to get the phone(7)
ioctl's to do it.  Has anyone done this?  Can anyone
help me with the problem?
Post to the net, or reply to me directly.  Thanks
