maui−soho−01(config)#interface Serial 2/0
maui−soho−01(config−if)#physical−layer async
!−−− Places the interface in asynchronous mode. 
!−−− Continue to configure this Serial interface as you would configure
!−−− an Async Interface.
maui−soho−01(config−if)#ip add 10.0.0.1 255.255.255.0
maui−soho−01(config−if)#async mode interactive
maui−soho−01(config−if)#async default routing
maui−soho−01(config−if)#dialer in−band
maui−soho−01(config−if)#dialer map ip 10.0.0.2 name maui−nas−01 broadcast 5551111
!−−− These commands are part of a broader DDR configuration.
To connect a modem to this interface, refer to Configuring Dialout using a Modem on the AUX Port. This
document uses the AUX port. However, the configuration is very similar.
To map the interface number to a line number, first multiply the slot number by 32, then add the unit number,
and add 1: line number = (<slot> * 32) + <unit> + 1.
Use the command physical−layer sync or no physical−layer async to revert to the default sync mode. To
configure the interface for normal serial operation, refer to Configuring Serial Interfaces.
