The ECHO parameter allows the user to set the echo (duplex) mode. Selecting
ON enables echoing so that all characters received on the serial port are echoed
back over the serial port. This mode is useful when using terminal emulation
software on a computer to communicate with the instrument. Selecting OFF
disables echoing. This mode is commonly used when using control software on
the computer.

7.5.1.2 IR
When the IR option is selected, the parameters for the IR port are displayed on
the bottom portion of the display. These parameters are: MODE, IR PER, and
PRINT.
The MODE parameter allows the user to select the protocol used by the IR port
to transmit and receive data. The user may choose between OFF, HP-PR,
COMM, and IRDA.
The OFF option turns the IR port off.
The HP-PR option allows the user to print a new measurement to an
HP-IR calculator printer.
The COMM option allows the user to transmit data over the IR port at
9600 baud in simple ASCII format.
The IRDA option allows the user to print logged data to an IrDA compati-
ble printer (such as an HP LaserJet 2100). Automatic real time printing is
not possible with the IrDA mode..
The IR PER parameter allows the user to select the interval at which measure
-
ments are transmitted over the serial port. The user may choose between 0.1,
0.2, 0.5, 1, 2, 5, 10, and 30 seconds, 1, 2, 5, 10, and 30 minutes, and 1 hour.
The IR PER can not be set to less than 10 seconds if the MODE is set to
HP-PR.
The PRINT parameter allows the user to enable printing measurements over the
IR port. Selecting ON enables printing and selecting OFF disables printing.
