Syntax
no flowcontrol hardware
Mode Line Configuration
Default Hardware flow control is disabled by default.
Usage notes 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:
