1.All asynchronous rates support flow control.

2.All dial-up modes support front panel, DTR, RS-366, AT command, and V.25 bis dialing

methods.

3. Rates marked with f require flow control.

4.Given a choice between two protocols, pick the protocol closer to the top of the list.

5.Multilink PPP supports the same rates as single-link PPP async-sync. Use the recom- mended rates for PPP async-sync.
