(Host Serial Port Set command) Set the RS-232-C settings for the 5500A Calibrator rear
panel SERIAL 1 FROM HOST serial port, which is saved in the 5500A non-volatile
memory. (While saving configuration data in the non-volatile memory, a period of about
2 seconds, the 5500A does not respond to remote commands.) (To set the parameters for
the rear panel SERIAL 2 TO UUT serial port, see the UUT_SET command.) The factory
default values are shown below in bold type. (To return to the factory defaults, see the
FORMAT SETUP command.)
The interface selection sets the command response, with command echo back for
commands and error messages with TERM (terminal) or no echo back with COMP
(computer).
Parameters: <baud rate value>, 300, 600, 1200, 2400, 4800, 9600
<interface>, TERM (terminal), COMP (computer)
<flow control>, XON (xon/xoff), NOSTALL (none), RTS (rts/cts)
<number data bits>, DBIT7 (7 bits) or DBIT8 (8 bits)
<number stop bits>, SBIT1 (1 bit) or SBIT2 (2 bits)
<parity>, PNONE (none), PODD (odd),PEVEN (even)
<end of line char.> CR (carriage return), LF (line feed),
CRLF (carriage return/line feed)
Example: SP_SET 9600,TERM,XON,DBIT8,SBIT1,PNONE,CRLF
Set the parameters for the rear panel SERIAL 1 FROM HOST serial port to the factory
default values.

(Host Serial Port Set query) Return the RS-232-C settings for the 5500A Calibrator rear
panel SERIAL 1 FROM HOST serial port. (To return the parameters for the rear panel
SERIAL 2 TO UUT serial port, see the UUT_SET? command.) The factory default
values are shown below in bold type. (To return to the factory defaults, see the FORMAT
SETUP command.)
Responses: <baud rate value>, 300, 600, 1200, 2400, 4800, 9600

<parity>, PNONE (none), PODD (odd),PEVEN (even)
<end of line char.> CR (carriage return), LF (line feed),
CRLF (carriage return/line feed)
Example: SP_SET? returns 9600,TERM,XON,DBIT8,SBIT1,PNONE,CRLF
Return the parameters for the rear panel SERIAL 1 FROM HOST serial port, as shown,
when set to the factory default values.
