Figure 10. Windows 2000 Resource Allocation
5. Several predefined Basic Configurations have been included for the SSP-100
. The SSP-100 can either be forced to use a “standard” base address for
COM1 - COM4, or it may be configured to allow Windows to assign the base
address. Standard base I/O addresses are defined only for the first four logic
COM ports: 3F8 (COM1), 2F8 (COM2), 3E8 (COM3), 2E8 (COM4). Some
older applications are limited to using COM1 - COM4 , in which case forcing
the SSP-100 to use a “standard” base address may be necessary. When
Windows is allowed to select the base I/O address, a “standard” COM1 -
COM4 base address is usually selected if one is available. Otherwise, a
non-standard base address is used. Windows enumerates any COM port at a
non-standard address starting with COM5.
