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:

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


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 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.

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.
