In example 2, the Client Driver will attempt to configure the QSP-100 as COM3 through COM6 using I/O address 300-31F hex and IRQ 4. If COM3, 4, 5, or 6 already exists, or if the I/O address or IRQ resources are already in use, the Client Driver will attempt to configure the QSP-100 as COM7 through COM10 using I/O address 120-13F hex and IRQ 15. If COM7, 8, 9, or 10 already exists or if the I/O address or IRQ resources are already in use, the QSP-100 will not be configured. Up to two QSP-100s can be installed in this system.
3.4 Advanced Configuration Topics
For some applications, it may be desirable to specify the resources for one QSP-100 while allow- ing 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 QSP-100 Client Driver command line
DEVICE=C:\QSP-100\QSP100.SYS (3,100,5) COM7
It is important to remember that when a QSP-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 QSP-100 inserted into socket 1 be config- ured as COM3 through COM6 while a QSP-100 inserted into socket 2 be configured as COM7 through COM10. This type of configuration is supported by appending a "=Sx" parameter after any command line argument.
DEVICE=C:\QSP-100\QSP100.SYS COM3=S1 COM7=S2
DEVICE=C:\QSP-100\QSP100.SYS (3,100,4)=S1 (7,300,3)=S2
