5.A dumb terminal on the serial line /dev/ttyE0 is losing characters when receiving large blocks of data from the server. Suspecting a flow control problem, you wish to examine the complete list of settings for this line on the server. Please type the one command that completes this command line: ____________ -a </dev/ttyE0
Answer: stty

Explanation: The stty command works on the current terminal by default, but by using the input redirection ("<") feature of the shell, we can have stty manipulate any tty device. The -a option is used to display all configuration settings.
