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 in register S86=25 (this is also defined for #UD). The user must flash the hook in order to get a dial tone
due because the remote server will be retraining.
If the local handset is picked up while the 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. At this point, the user dial tone should be on the local handset. The
disconnect reason in S86=25.
