[HELP SEND short]
The SEND command is used to send a message to another TTY line.
form of the command:
SEND TTY46 HELLO THERE
        or TTY may be omitted as in:
SEND 46 HELLO THERE
        or, using the JOB NUMBER:
SEND JOB 12 HELLO THERE
        or, to the computer room:
SEND OPR HELLO COMPUTER OPERATOR

       A nifty feature of SEND is to notify yourself when
       your program is finished by typing :
SEND .
       after your last program input.  The "DOT" (.) means send to yourself,
       so you get  a  "bell"  to  tell you the program is finished and the
       terminal is at monitor level.
