AFAIK, the physical-layer async command is only available on the 2500 series routers that have "low speed" synchronous/asynchronous capable serial interfaces, i.e. 2520 - 2523. The 2501 only has "high speed" synchronous serial capable interfaces, and as such wouldn't need the physical-layer async command.
So to answer your question...11.3 probably does support physical-layer async, if used with the appropriate hardware, i.e. 2520 - 2523.
