I find myself wondering if CCITT5 tones are still in use on international trunks. Anyone know? Any old BlueBeep users here?

- myself248 5y agoP80Box was a lot more compact than BlueBeep :P At one of the HOPEs, someone brought a bunch of 8-bit machines and set them up in the mezzanine. Among them was a TI 99/4A, which for all its failings, had a very nice sound chip accessible from TI BASIC. And, bless whoever brought it, the TI BASIC quick reference card was tucked under the machine, which was all I needed to jog my memory. I implemented a quick tone-dialer with DTMF and redbox tones, adjustable twist, and a few other features. Since there was no tape deck and everything was just resident in RAM, I fully expected that someone would reboot the machine and do something else with it moments after I walked away. It was fun in the moment, that's all I wanted. Much to my surprise, I came back several hours later and there were folks playing with the dialer, and to my even greater surprise, someone had extended it with MF and bluebox tones in the interim!
