|Driver||Here you choose the direct access or the TAPI mode of modem communication. To learn more about communication modes, please read F.A.Q. #21.|
|Modem||Select your modem from the list.|
|COM port number||This is usually COM port 1-4.|
|Silence Detection||Hangs up if a specified duration of silence is detected.|
||0 - 100%||min
The least sensitive setting. Least likely to detect periods of silence, but is still able to do so, if the line is really quiet. <midrange value>
An exact value; midrange setting. Likely to be the best overall compromise on normal telephone lines.
||Measured in seconds. Default is 5 seconds.||Silence detection period, seconds. When no voice is present in the line for a specified period, the program assumes silence and hangs up.|
|Use hardware gain control (AGC)||Disabled by default||Allow modem hardware to perform Automatic Gain Control to adjust the voice volume to a standard level. Please note that many modems have no AGC at all, while some other modems do not allow it to be turned off.|
|Use software gain control (AGC)||Enabled by default||Software Automatic Gain Control adjusts the sound volume to an average level automatically. Turn it ON if sound levels are too loud or too quiet, and turn it OFF if a recorded voice is noisy. If your modem has built-in hardware AGC, you may turn this OFF.|
Your modem manual will indicate which types of voice compression it supports.
A variety of voice codecs are available; if garbled sounds are produced, try changing the voice compression codec.
GSM 6.10 compression is a frame-based speech codec with at least two different implementations: encapsulated GSM and un-encapsulated GSM. The GSM compression type is usually detected automatically.
|Compatibility option||Enables short delays between commands for better compatibility. The closer the slider is to the "compatibility" edge, the slower (but more reliable) the performance will be.|
