High-level Protocol Layers
Exist in order to make life easier for developers
Some exist mainly to help support legacy applications
IrCOMM:
- Serial and parallel port emulation
- Designed to aid initial migration of serial/parallel port applications to IrDA
- Overcomes the significant differences between the two protocols, which include (for example) the presence of only a single beam in IR, vs. multiple wires in a serial or parallel port
- Disadvantage: some IrDA features lost when IrCOMM used (e.g., IAS and connection-speed negotiation)
