IrDA全套的 spec需要 ＄792。其他的各位补充。
我这里只上传了 跟硬件有关的 物理层 IrDA Physical Layer Specification，大家一起探讨。
全套目录：
IrDA Data Specifications (SIR/MIR/FIR/VFIR):
The IrDA Data or "Classic" family of specifications provides the base on which all upper layer protocols and applications are built. The Data specifications are required for any IrDA-enabled devices. Click here for detailed description.
The following specifications are included.
