ABSTRACT:
A remote automatic utility reading system includes a reading control center for transmitting commands to and receiving measurement data from remote terminal units via a command responsive control unit. The control unit is characterized by a computer having a stored program of subroutines, one of which is an interrupt subroutine. The interrupt subroutine is periodically entered as commands are received by the control unit from the reading control center and directs entry into other ones of the subroutines for execution thereof to effect the simultaneous interlacing of the commands and measurement data being transferred between the reading control center and the remote terminal units.
