7. Using UNIX Aliases for Terminal Server Commands The Model 3395 Terminal Server software provides several UNIX equivalents or aliases for Model 3395 3395A Terminal Server commands If you work in a UNIX environment you may want to use these aliases because they will be more familiar to you than the Model 3395 3395A commands Instead of the terminal server HELP command for example you can enter the MAN command Chapter 3 includes a description of the UNIX aliases for terminal server commands Logging Out of the Terminal Server Port The terminal server LOGOUT command logs you out of the terminal server port When you do this the terminal server disconnects any sessions that are still active TS3395 logout TS3395 020 Logged out port 12 on server XFF4B15 at 22 September 1993 16 12 00 The log out message includes your port number and the name of the terminal server as well as the date and time you logged off If You Make a Mistake Do not be concerned if you make a mistake such as a typing error when you enter a command The terminal server displays an error message and often some information that helps you correct the command In any case you can reenter the command correctly or recall and edit the command line with the editing characters described in Chapter 2 Privilege Levels Privilege levels determine which terminal server commands you can use The network manager can set the privilege level at each port to one of thre
