ATH - Hang Up In Voice


This command works the same as in Data and FAX modes by hanging up (disconnecting) the telephone line. There are, however, some specific considerations when in Voice Mode:

1. The H command forces #CLS-0, but does not destroy any of the voice parameter settings such as #VBS, #VSP, etc. Therefore, if the DTE wishes to issue an H command and then pursue another voice call, it must issue a subsequent #CLS=8 command, but it needn't reestablish the voice parameter settings again unless a change in the settings is desired.

2. The #BDR setting is forced back to 0, re-enabling autobaud.

3. If the #VLS setting is set to select a device which is not, or does not include the telephone line (such as a local handset or microphone), the H command deselects this device and reselects the normal default setting (#VLS=0). Normally, the DTE should not issue the H command while connected to a local device such as a handset, because merely selecting this device results in VCON. The normal sequence of terminating a session with such a device is to use the #VLS command to select the telephone line, which by definition makes sure it is on-hook.
