Quatech DSP-100 - Manual (Page 47)

8.1.2.2 Example 2
DEVICE=C:\DSP-100\DSP100.SYS (7,120,15) (3,300,4)
In example 2, the Client Driver will attempt to configure the DSP-100 as COM3 and
COM4 using I/O address 300-30F hex and IRQ 4. If COM3 or COM4 already exists, or
if the I/O address or IRQ resources are already in use, the Client Driver will attempt to
configure the DSP-100 as COM7 and COM8 using I/O address 120-12F hex and IRQ 15.
If COM7 or COM8 already exists or if the I/O address or IRQ resources are already in
use, the DSP-100 will not be configured. Up to two DSP-100s can be installed in this
system.
8.1.3 Advanced Configuration Topics
For some applications, it may be desirable to specify the resources for one DSP-100
while allowing the OS/2 Plug-and-Play system to assign the hardware resources for
any additional cards. This can be accomplished by mixing the configuration methods
on the DSP-100 Client Driver command line
DEVICE=C:\DSP-100\DSP100.SYS (3,100,5) COM7
It is important to remember that when a DSP-100 is inserted into a PCMCIA socket, the
client driver will configure the card as a series of COM ports, starting with the lowest
available port number in the list.
Another common application requirement is to have a DSP-100 inserted into socket 1 be
configured as COM3 and COM4 while a DSP-100 inserted into socket 2 be configured
as COM7 and COM8. This type of configuration is supported by appending a "=Sx"
parameter after any command line argument.
DEVICE=C:\DSP-100\DSP100.SYS COM3=S1 COM7=S2
DEVICE=C:\DSP-100\DSP100.SYS (3,100,4)=S1 (7,300,3)=S2
