flowcontrol hardware (asyn/console)
Use this command to enable RTS/CTS (Ready To Send/Clear To Send) hardware flow
control on a terminal console line (asyn port) between the DTE (Data Terminal Equipment)
and the DCE (Data Communications Equipment).
Syntax flowcontrol hardware
no flowcontrol hardware
Mode Line Configuration
Default Hardware flow control is disabled by default.
Usage Hardware flow control makes use of the RTS and CTS control signals between the DTE and
DCE where the rate of transmitted data is faster than the rate of received data. Flow
control is a technique for ensuring that a transmitting entity does not overwhelm a
receiving entity with data. When the buffers on the receiving device are full, a message is
sent to the sending device to suspend the transmission until the data in the buffers has
been processed.
Hardware flow control can be configured on terminal console lines (e.g. asyn0). For
Reverse Telnet connections, hardware flow control must be configured to match on both
the Access Server and the Remote Device. For terminal console sessions, hardware flow
control must be configured to match on both the DTE and the DCE. Settings are saved in
the running configuration. Changes are applied after reboot, clear line console, or after
closing the session.
Use show running-config and show startup-config commands to view hardware flow
control settings that take effect after reboot for a terminal console line. See the show
running-config command output:
Note that line configuration commands do not take effect immediately. Line configuration
commands take effect after one of the following commands or events:
■ issuing a clear line console command
■ issuing a reboot command
■ logging out of the current session
Examples To enable hardware flow control on terminal console line asyn0, use the commands:
awplus#show running-config
!
line con 1
speed 9600
mode out 2001

awplus# configure terminal
awplus(config)# line console 0
