- Most answering machines and phone switchboards also have problems with
- "short" DTMF tones.
-
- Many cellular phones have an option of selecting "long" vs "short" tone
- duration.
-
- Another problem with some telephones is that they do not work well (if at
- all) on a line where the modem is already on-line, as they do not get
- sufficient current to power their tone-generators.
-
- Basically, you should get a tone for as long as you hold your key down.
- A keypress of 1/2second or so should be *more* than enough for any system,
- including ZyXEL modems.
