ath: Hang-up
The ath command terminates an ISDN call. If the router is still on-line, you must first switch back to
command mode by entering the escape sequence, such as +++, wait 1 second, then enter an AT
command or simply at<CR>.
After entering the ath command, the call is disconnected and the NO CARRIER result is issued.
