Select Tones with Access Security
Controls the type of tones used by your modem to alert the caller to expect a callback and to
enter the access security password.
No tones are generated by the answer modem.
Upon answering a call, the local modem sends the caller a dial tone. This is a prompt for the
caller to enter the access security password. This setting is intended for manual dialing only.
The dial tone lasts for the amount of time specified by S-Register 45. The caller must enter the
access security password in the amount of time specified by S-Register 46.
