Behavior in Data Mode (+FCLASS=0): When on-hook, if the line is in use and an ATDT is issued, the modem
will not go off-hook and will return with the message LINE-IN-USE.
When off-hook and either an extension is picked up or a line reversal is
detected, the modem will drop the connection. The disconnect reason
is register S86=25 (also defined for #UD). The user must flash the hook
in order to get a dial tone because the remote server will be retraining.
If the local handset is picked up while modem is off-hook, the modem
will do a link-disconnect, flash the hook for 1.5 seconds, then connect
the local handset to the line. Now, the user dial tone is on the local
handset. Disconnect reason S86=25.
Behavior in Voice Mode (+FCLASS=8): When in voice mode and an extension is picked-up, a <DLE>P is sent to
the DTE. When the modem is off-hook, a line reversal may also be
detected in which case a <DLE>l is sent to the DTE.
In voice mode, there is no blocking of ATDT when the line is in use.
Also, there is no automatic hang-up in voice mode as in data mode.
There is only the above stated <DLE> shielding event reporting.
