Allowed devices determines which devices a user may select for direct access.  
Allowed listen devices determines which devices a user may use listen access. 
“Listening” is defined as being able to read from an existing device port connection 
without write ability.  This feature is useful for sharing information among multiple users 
or for monitoring a user’s session with an attached device.

HELPFUL HINT:
 Make a diagram or spreadsheet of connections indicating  connections 
between devices and the SCS3230 device ports as numbered above. 
 
The 
Allow user to clear device buffer (Y/N) | YES > option determines 
whether a user may use the 
CLEAR command to delete all the data stored in a device 
port FIFO buffer.  The sys admin may want to inhibit this ability to preserve user 
accountability when accessing attached devices.  Users are allowed to clear buffers by 
default.  Pressing 
<ENTER> will allow the user to clear the buffer; typing NO and then 
pressing 
<ENTER> at the prompt when defining a user ID will disallow the user from 
clearing all device buffers. 
 
The 
Clear screen after a command (Y/N) | YES > option determines if the 
screen clears when most commands are executed.  Disallowing this screen behavior 
keeps the last few commands and responses on the terminal screen.  The default value 
for this option is 
YES.  Pressing <ENTER> will accept the default value; typing NO and 
then pressing 
<ENTER> disallows this screen behavior.
