Next, if you've used the modem at command to tell Autolog what kind of modem you're using, Autolog will send the appropriate "hang up" command to the modem.
The hangup command also causes an entry of your call to be written in the phone log file.
The finish
command automatically does a hangup. You need to use hangup
only when you want to end one modem call and place another without
exiting Autolog.
