CHAPTER 35

Serial Parallel Controller Test (spif)

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

spif 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 spif test 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

spif Options

FIGURE 35-1 spif

The Configuration section of the Option menu displays the serial ports available for the SPC/S board. The available ports are listed in TABLE 35-1.

TABLE 35-1 spif

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 spif test options are described in TABLE 35-2.

TABLE 35-2 spif

spif 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).
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.

TABLE 35-2 spif

spif Option	Description
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 spif test 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 spif Options menu.

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 2.1 User's Guide.

spif Test Modes

The spif test supports only the Functional test mode.

spif Command Line Syntax

/opt/SUNWvts/bin/spif 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 35-3 spif

Argument	Explanation
dev=device_name	Specifies the serial ports in SBus card slots (0-63) being tested. Since there is no default, you must type a device name--either a board (stc0-7) or an individual port (term/0 - term/63): 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 or /dev/term/mm Where mm is 0 to 63 (any of the serial ports in SBus card slots)
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.

spif Error Messages

These error messages are generated when the SunVTS serial parallel controller discovers any errors. The error descriptions below identify probable causes for the card or test failure, and identify the Field Replaceable Unit (FRU), if possible. The three FRUs affected are: the serial parallel controller card, the 96-pin shielded cable, and the patch panel.
