- Well, forget about modems with CODECs... I think I have a solution to my
- hardware problem. It occurred to me last night that the joystick port can
- be used as a simple 4-line digital input... which would read in my DTMF
- tones just fine. However, I still need another input to tell me when the
- phone is ringing and an output to pick up/hang up the phone line. (I'm
- interfacing the computer to someone's phone board). Can someone give me
- a run-down on the parallel port and suggest possible ways of doing this
- I/O? The probable target system will be an Amiga 1200. Are there any
- (CHEAP) small digital I/O interfaces available? Once again, your help may
- result in an Amiga being used in this product instead of an IBM, but it
- has to be cheap and simple. E-mail if you want to correspond further on
- this problem.
