Serial Port
A maximum of four serial ports (COM1 through COM4) are tested. All
parameters i.e. number of data bits, number of stop bits, parity type etc. can be
individually selected for each port. The tests that are performed on the serial
ports include: Register test, Interrupt ID test, Internal loopback test, Line status
test, Modem control register test, Data transfer test (at baud rates from 300 BPS
to 115.2KBPS and FIFO test.
Parallel Port
A maximum of three parallel ports (LPT1 through LPT3) are tested. The test
parameter window asks the user whether a printer or a loopback plug is
connected. If these are not connected, only the register read/write test is
performed. Otherwise, the following tests are performed: Register test, IRQ
activation test, Pattern printing, Bold letter printing, Compressed mode printing,
Printer form feed test, and ECP test.
Video Test
The Video Test Menu includes functional exercising of the video memory.
Video Memory Test
The Video Memory Test checks the base 256k of video memory for integrity by
performing a memory pattern test.
IDE CD-ROM
The IDE Tests include exercising of the CD-ROM tray response, data, and audio
if present.
IDE CD Data Test
This test reads logical blocks from the CDROM. If the starting logical block
number and end logical block number fields are not specified, the test starts
reading from block 0 and terminates at the last block of CDROM. This test will
fail if an audio CD is inserted inside the drive.
