DSP200.SYS

Quatech DSP-200/300 PCMCIA Dual RS-422/RS-485 Serial Port driver.

 DEVICE=x:\path\DSP200.SYS COM3

or

DEVICE=x:\path\DSP200.SYS (port_number,base_address,irq)

• No spaces should appear inside the parentheses.
• The base_address is a hexadecimal value that must end with 0.
• The DSP-200 requires 16 bytes of I/O space, starting with the base address.
• The first port resides in the first 8 bytes, the second in the next 8 bytes.
• The irq is a decimal value from 2 to 15.

Examples

Method 1

Let OS/2 PCMCIA Plug-and-Play choose hardware settings

DEVICE=x:\path\DSP200.SYS COM3

The client driver's first and only choice is to configure the DSP-200 to use COM3 and COM4. Only one DSP-200 can be used.

DEVICE=x:\path\DSP200.SYS COM3 COM5

The client driver's first choice is to configure the DSP-200 to use COM3 and COM4. The second choice is to use COM5 and COM6. Up to two DSP-200s can be used.

Method 2

Specify the hardware settings

DEVICE=x:\path\DSP200.SYS (3,110,5)

The client driver's first and only choice is to configure the DSP-200 for COM3 (I/O addresses 110-117 hex) and COM4 (I/O addresses 118-11F hex), using IRQ 5. Configuration will fail if any of these resources are already in use. Only one DSP-200 can be used.

DEVICE=x:\path\DSP200.SYS (3,300,4) (5,110,15)

The client driver's first choice is to configure the DSP-200 for COM3 (I/O addresses 300-307 hex) and COM4 (I/O addresses 308-30F hex), using IRQ 4. The second choice is to configure the DSP-200 for COM5 (I/O addresses 110-117 hex) and COM6 (I/O addresses 118-11F hex), using IRQ 15. Up to two DSP-200s can be used.
