8.2Serial Ports

Prometheus contains 4 serial ports. Each port is capable of transmitting at speeds of up to 115.2Kbaud. Ports COM1 and COM2 are built into the ZF Micro CPU chip. They consist of standard 16550 type UARTs with 16-byte FIFOs. Ports COM3 and COM4 are derived from an Exar 16C2850 dual UART chip and include 128-byte FIFOs. Ports 3 and 4 may be operated at speeds up to 1.5Mbaud with installation of high-speed drivers as a custom option.

The serial ports use the following default system resources:

Port

Address range

IRQ

COM1

I/O 3F8 – 3FF

4

COM2

I/O 2F8 – 2FF

3

COM3

I/O 3E8 – 3EF

4

COM4

I/O 2E8 – 2EF

3

The settings of COM1 and COM2 may be changed in the system BIOS. Select the Advanced menu, then I/O Device Configuration. Serial Port A is COM1, and Serial Port B is COM2. The base address and interrupt level may be modified on this page.

The settings of COM3 and COM4 may be changed using a different procedure:

The addresses of these two ports are selected on the Advanced menu of the BIOS. Select Advanced Chipset Control, then ISA I/O Chip Select Setup. I/O Window – io_cs1 is for COM3 and I/O window – io_cs2 is for COM4. The only parameter that may be changed is the address. The other settings must remain in their default values:

Window state:

Enabled

Base Address:

(user selectable)

Read/Write control:

Read/Write

Window data width:

8-bits

Active Level:

Active Low

Window size:

08

After making any desired changes, go to the top-level Exit menu and select Exit Saving Changes.

The interrupt (IRQ) settings for COM3 and COM4 are selected with J10. COM3 may use IRQ4 or IRQ9. COM4 may use IRQ3 or IRQ15. If both serial ports share the same IRQ, they may share IRQ4 or IRQ5. See page 16 for serial port IRQ jumper settings.

8.3Parallel Port

The parallel port (LPT1) is an IEEE-1284 compatible bidirectional port. It includes filtering for reduced EMI operation. It operates in ECP mode (set up in the BIOS). The parallel port has the following default configuration:

Port

Mode

Address range

IRQ

DMA

LPT1

ECP

I/O 378 – 37F
