6 DOS and Other Operating Systems

The DSC-100 is not a direct drop-in replacement for a legacy serial port because its base address and IRQ cannot be fixed at values such as 3F8 hex, IRQ 4 (COM1) or 2F8 hex, IRQ 3 (COM2), etc. Rather, the system BIOS assigns the address and the IRQ in a plug-and-play fashion at boot time. Software which is to use the DSC-100 must be able to accommodate any valid assignments of these resources.

For Windows and OS/2, the Quatech device drivers determine what the resource assignments are and proceed accordingly. In other cases, however, the user must intervene. The discussion below will center on DOS, but the concepts can be applied to other operating systems as well.

Many DOS applications support user configuration of the base address and IRQ of a serial port. Such applications can generally make use of the DSC-100. Older applications, as well as some custom software, may use hard-coded standard legacy serial port addresses. These applications will require modifications if they are to use the DSC-100.

Custom applications for which the customer has source code can be modified to make just a few PCI BIOS function calls to obtain all the necessary configuration information. The PCI BIOS specification can be obtained from the PCI Special Interest Group. Contact Quatech technical support for more information.

6.1.1 QTPCI.EXE

Quatech's "QTPCI" utility supplies the information required when modifying the serial port settings of the application. This program should be run from real DOS, not in a Windows DOS box.

Figure 15 shows the Basic Mode display for the DSC-100 after the "Q" key has been pressed. In this example, the DSC-100 uses I/O base address FC20 hex and IRQ

11.The hardware revision of the DSC-100 is also displayed. Pressing the "N" key will show similar information for all non-Quatech PCI devices in the system, including those devices integrated on the motherboard.
