PCMCIA Modem Card Test (pcsertest)

PCMCIA is a technology that provides small, easy to use peripheral devices. PCMCIA stands for Personal Computer Memory Card International Association. It is a PC Card standard for mobile computing I/O cards. These cards range from memory, FAX/modems, serial I/O, SCSI, video, sound, and so on.

The pcsertest verifies the functionality of PCMCIA modem card and PCMCIA serial I/O socket card. It does not test any other PCMCIA devices.

The pcsertest issues a series of commands to the modem to initiate a local analog loopback test and verifies this functionality.

As an option, the pcsertest tests serial I/O socket cards. This test writes a pattern of incrementing data to the serial I/O socket card, which is then looped back, read and verified.

---

Note - When testing serial I/O socket cards, a 9-pin loopback connector is required. However, no loopback connector is required when testing the default modem card. See Appendix A for loopback connector wiring instructions.

pcsertest 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.

FIGURE 36-1 pcsertest Test Parameter Options Dialog Box

TABLE 36-1 pcsertest Options

pcsertest Option	Description
Card Type	Specifies the type of device you are testing; either a PCMCIA modem, or a PCMCIA serial I/O socket card. Note-If you choose the Serial card type, and there is no serial I/O socket card in the slot, the test fails.
Baud Rate	Specifies the baud rate for testing.
Num Chars	Specifies the number of characters being used for external loopback testing of the serial socket card. By default, this is set to 256 characters. This option is applicable only to serial socket cards and ignored for the modem card.

---

Note - Any combination of modem and socket I/O cards can be placed in the PCMCIA slots. However, you must select the correct type of card in the Options dialog box. If you select an incorrect card type, the test fails. The default card type for each PCMCIA slot is a modem card. If only one modem card is plugged in, the empty slot is ignored.

pcsertest Command-Line Syntax

/opt/SUNWvts/bin/pcsertest standard_arguments -o dev=device_name, type=card_type,baudrate=speed,numchars=n

TABLE 36-3 pcsertest Command-Line Syntax

Argument	Description
dev=device_name	Specifies the device name (for example, dev=pc0 and dev=pc1)
type=card_type	Specify one of the two card types for the device ( type=serial or type=modem). You do not need to specify the type if the device is a modem, since modem is the default card type.
baudrate=speed	Specifies the communication speed. Specify one of the following: 9600 19200 38400 57600 The default is 9600.
numchars=n	Specifies the number of characters to use for external loopback testing of the serial socket card. By default, this is set to 256 characters. This option is applicable only to serial socket cards and ignored for the modem card.

Note - 64-bit tests are located in the sparcv9 subdirectory: /opt/SUNWvts/bin/sparcv9/testname, or the relative path to which you installed SunVTS. If a test is not present in this directory, then it might be available as a 32-bit test only. For more information, see 32-Bit and 64-Bit Tests.
