Requirements and Considerations
Requirements
- The RealPort driver requires between one and two MB of memory
on the Microsoft Windows 2000 system.
- The Windows 2000 RealPort driver requires a 10-pin RJ-45 cable
to connect devices to PortServer ports. This requirement does not apply to
Etherlite units.
Limitations
- Only TAPI-compliant applications or those written to COM 32 API
(application programming interface) standards can use intelligent
ports, which means only these applications can use RealPort
ports.
Key Concept: About Port Mapping Offsets
The number of local ports on the Windows 2000 host offsets the
port number on the PortServer. For example, if you have two local
COM ports, Port 1 of the Digi One RealPort or PortServer is seen by the RealPort service
as COM 3.
