ETS-Lindgren FM5004 Field Monitor (Archived) - Manual (Page 59)

The receiver asserts two lines: Data Terminal Ready (DTR) and Request To
Send (RTS). These lines are asserted continuously and do not perform a
handshake function; they can simply be connected to the CTS and DCD lines at
the connector. This will allow the receiver to transmit with a minimum of wires
and with no handshaking. See RS-232 Pin Detail on page 59 for pinout
information.
Once the RS-232 interface is established, commands are processed in a manner
similar to the IEEE interface. The command structure is identical, except there is
no EOI line; therefore, all commands must be terminated by a .
When a valid command is received, it is processed and the result is immediately
transmitted back over the RS-232 interface. The CTS line can be used to control
the flow of information from the receiver, as described on page 58. The output
format is identical to that of the IEEE format except there is no EOI line.
