                                CTTY--Notes
 
Setting up a serial port for CTTY
 
Use the MODE command to set up your serial port for baud rate, parity, bits,
and stop bit before using the CTTY command.
 
Using CTTY with programs that do not use MS-DOS
 
Many programs do not use MS-DOS for input or output. These programs send
input directly to the hardware on your computer. The CTTY command has no
effect on these programs; it affects only programs that use MS-DOS for
reading keyboard input and displaying output.
 
Setting the terminal device with COMMAND
 
In addition to the CTTY command, you can use the device parameter of the
COMMAND command to specify the input device.
                                      ***

                               CTTY--Examples
 
To change control of all input and output from the current device (your
computer monitor and keyboard) to the AUX port, type the following at the
command prompt:
 
    ctty aux
 
In this example, a remote terminal device connected to the AUX port controls
input and output for your system.
 
To transfer input and output back to the monitor and keyboard, type the
following command at the remote terminal:
 
    ctty con
 
                                      ***
