Serial Parallel Controller Test (spiftest)

The spiftest accesses card components such as the cd-180 and ppc2 chips, and the serial and parallel ports through the serial parallel controller device driver.

spiftest Hardware Requirements

Before running the SunVTS system exerciser, make sure you install the cards to be tested and the device driver. You should also reboot your system with the
boot -r command to reconfigure the system and allow the SunVTS kernel to recognize the new driver.

Note - The spiftest must be run in Intervention mode.

The following minimum hardware configuration is required to successfully run the Internal test:

SBus-based SPARC desktop system with an SBus slot
Serial parallel controller card, installed in one of the SBus slots

The following hardware is also required to run the other SunVTS serial parallel controller tests:

Serial parallel controller patch panel (part number 540-2007)
96-pin loopback plugs (part number 370-1366)
25-pin serial loopback plugs (part number 540-1558)
RS-232 serial cables (part number 530-1685)
TTY terminal

spiftest Options

To reach the dialog box below, right-click on the test name in the System Map and select Test Parameter Options. If you do not see this test in the System Map, you might need to expand the collapsed groups, or your system may not include the device appropriate to this test. Refer to the SunVTS User's Guide for more details.

The Configuration section of the Options dialog box displays the serial ports available for the SPC/S board. The available ports are listed in the table below.

TABLE 52-1 `spiftest` Serial Ports for the SPC/S Board
Board Number	Board Device	Serial Ports	Parallel Ports
0	stc0	term/0-7	printers/0
1	stc1	term/8-15	printers/1
2	stc2	term/16-23	printers/2
3	stc3	term/24-31	printers/3
4	stc4	term/32-39	printers/4
5	stc5	term/40-47	printers/5
6	stc6	term/48-55	printers/6
7	stc7	term/56-63	printers/7

The spiftest options are described in the table below.

TABLE 52-2 `spiftest` Options
spiftest Option	Description
96-pin Loopback (LB)	Provides data transmission, full-modem loopback, and parallel port loopback testing. You must attach a 96-pin loopback connector (part number 370-1366) to the card before running this test (see Appendix A, "96-Pin Female Loopback Connector" section).
Internal test	Performs a quick internal check of the serial parallel controller card(s) installed in SBus slots. You do not need to attach anything to the card(s) to perform this test.
25-pin Loopback (LB)	Provides full-duplex transmission and full-modem loopback testing of the serial port selected in the Serial Port selection of this menu. You must attach the 25-pin Loopback plug to the serial port on the Serial Parallel Controller Patch Panel that is being tested (see Appendix A). This test cannot be run concurrently with the Echo-TTY option enabled.
Echo-TTY	Checks the proper operation of the serial port selected in the Serial Port section of this menu by echoing characters typed on a TTY terminal keyboard to the TTY terminal screen. The characters you type should be displayed on the TTY screen. Note: TTY connection to the `spif` serial port requires corresponding character size setup. For example, if a TTY attachment is running with 8-bit character size, then the `spiftest` option `Char Size' should also be set to 8 bits. If you do not type within two minutes, this test will time-out. Terminate testing by pressing Control-C. After a short delay, the Status window updates the Pass Count. This test cannot be run concurrently with the 25-pin Loopback subtest.
Printer	Sends the entire ASCII character set to a parallel printer. You must attach a parallel printer to the parallel port on the Serial Parallel Controller patch panel. Observe the printer output to validate the test.
Baud Rate	Specifies the baud rate; choose 110, 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400 baud. Note: The baud rate of 38400 can only be used if one port is tested at a time and the Internal Test is disabled.
Char Size	Indicates character length. Choose 5, 6, 7, or 8 characters.
Stop Bit	Specifies the number of stop bits. Choose 1 or 2 bits.
Parity	Specifies the selectable parity. Choose `none`, `odd` or `even.`
Flow Control	Specifies the selectable flow control. Choices are `xonoff`, `rtscts`, or `both.`
Data Type	Specifies the selectable data type pattern. It can be 0x55555555 (0x55), 0xaaaaaaaa (0xaa), or random.
Serial Port	Specifies the serial port to be tested. The available ports are listed in the Configurations section at the top of the `spiftest` Options dialog box.

You can also change the test options by modifying the /opt/SUNWvts/bin/.customtest file. See "Adding Your Own Tests" in .customtest in the SunVTS User's Guide.

spiftest Test Modes

spiftest Command-Line Syntax

/opt/SUNWvts/bin/spiftest standard_arguments -o dev=device_name, M=test_mode,Ptr=enable/disable,B=baud_rate,Size=character_size,S=#of_stop_bits, Parity=parity,F=flow_control,Data=test_pattern,sp=serial_port

TABLE 52-4 `spiftest` Command-Line Syntax
Argument	Description
`dev=`device_name	Specifies the serial ports in SBus card slots (0-63) being tested. Since there is no default, you must type a board name: `stc0`--the 8 serial ports in the first card `stc1`--the 8 serial ports in the second card `stc2`--the 8 serial ports in the third card `stc3`--the 8 serial ports in the fourth card `stc4`--the 8 serial ports in the fifth card `stc5`--the 8 serial ports in the sixth card `stc6`--the 8 serial ports in the seventh card `stc7`--the 8 serial ports in the eighth card
`M=`test_mode	Specifies `Internal, 96_pin_Loopback, 25_pin_loopback,` or `Echo_TTY` test mode.
`Ptr=`printer_test	Enables or disables the Printer subtest.
`B`=baud_rate	Sets the baud rate to 110, 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400. The default is 9600. To use the 38400 rate, only one port at a time can be tested, and the `Internal` test must be disabled.
`Stop=`#of_stop_bits	Toggles the number of stop bits between 1 or 2. The default is 1.
`Size=`character_size	Sets character size as a number between 5 and 8.
`P=`parity	Specifies the parity as none, odd, or even. The default is none.
`F=`flow_control	Specifies flow control as `xonxoff,rtscts`, or both.
`Data=`test_pattern	Specifies test pattern as 0x55555555, 0xAAAAAAAA, or random.
`sp=`serial_port	Specifies the terminal and serial port number, such as `term/3`.

Note - 64-bit tests are located in the sparcv9 subdirectory: /opt/SUNWvts/bin/sparcv9/testname. If a test is not present in this directory, then it may only be available as a 32-bit test. For more information refer to 32-Bit and 64-Bit Tests.
