View source for 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 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.

==Parameters==
;COM
:Select the COM port, COM1, COM2, COM3

;Port
:COM Port: 3 = COM3

;Base_Address
:The base_address is a hexadecimal value that must end with 0.

;IRQ
:The irq is a decimal value from 2 to 15.

===Optional===
;=Sx
:TIE A CONFIGURATION TO SOCKET NUMBER 'X'.

:A DSP-200 inserted into socket 'x' will always use this configuration.  This also means that only one configuration will be tried for a given socket.

Example:  Always configure a DSP-200 in socket 1 as COM3 and COM4, and a DSP-200 in socket 2 as COM8 and COM9.
 DEVICE=x:\path\DSP200.SYS COM3=S1 COM8=S2


;=HS
:ENABLE RTS-CTS HARDWARE HANDSHAKE

:The RTS signal will be connected to AUXOUT, and the CTS signal will be connected to AUXIN.  This allows RTS-CTS hardware flow control to be used.

Example:  
 DEVICE=x:\path\DSP200.SYS (3,110,4)=HS

;=DTR
:USE DTR TO ENABLE OUTPUTS ON PORT A

:Outputs are enabled when the DTR signal is active, and are tristated when the DTR signal is not active.  This allows half-duplex communication.

Example:
 DEVICE=x:\path\DSP200.SYS (15,110,5)=DTR

;=RTS
:USE RTS TO ENABLE OUTPUTS ON PORT A

:Outputs are enabled when the RTS signal is active, and are tristated when the RTS signal is not active.  This allows half-duplex communication.

Example:  
 DEVICE=x:\path\DSP200.SYS COM17=DTR

;=BON       
:PORT B OUTPUTS ALWAYS ENABLED

:By default, the outputs on port B obey the same control as those on port A.  This option forces the port B outputs to always be active regardless of the state of port A.

Example:
  DEVICE=x:\path\DSP200.SYS COM17=BON


==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.
