•
Serial communication settings for the Agilent E1324A Datacomm
interface can be stored in its on-board non-volatile EEROM only after
the DIAG:COMM:SER[n]:STORe command is executed. These settings
are used at power-up and DIAG:BOOT[:WARM].
•
DIAG:BOOT:COLD will set the serial communication parameters to the
following defaults:
– BAUD 9600
– BITS 8
– PARity NONE
– SBITs 1
– DTR ON
– RTS ON
– PACE XON
Example
Setting baud rate for plug-in card 2.
SYST:COMM:SER2:BAUD 9600
(must be a card number 1 also)
:COMMunicate
:SERial[n] :CONTrol
:DTR
SYSTem:COMMunicate:SERial[ n] :CONTrol:DTR < dtr_cntrl> controls the
behavior of the Data Terminal Ready output line. DTR can be set to a static
state (ON | OFF), can operate as a modem control line (STANDard), or can be
used as a hardware handshake line (IBFull).

Comments
•
The following table defines each value of dtr_cntrl:
Value
Definition
ON
DTR line is asserted
OFF
DTR Line is unasserted
STANdard
DTR will be asserted when the serial interface is
ready to send output data. Data will be sent if the
connected device asserts DSR and CTS.
IBFull
While the input buffer is not yet at the :STOP
threshold, DTR is asserted. When the input buffer
reaches the :STOP threshold, DTR will be
unasserted.

DIAG:BOOT:COLD will set

DTR to ON.
