software used. It is also recommended that the user avoid combinations of the <CTRL> key and other keys, as these combinations are usually reserved for sending and receiving special characters through the terminal. When the user changes the escape sequence, a window with the hexadecimal representation of the old escape sequence will appear. Pressing <ESC> to exit from the edit prompt will not work; it will add additional <ESC> characters (hexadecimal value 1B) to the direct mode escape sequence. If the user wishes to keep the old sequence, they need only to press <ENTER>. Otherwise, they should press backspace to delete the old characters, then enter the new sequence and press <ENTER>. If for some reason the selection is unacceptable, an error message will appear and the sequence will revert to the old character values. The escape sequence is stored with the user profile, therefore it is possible to have different sequences for different users. A hardcoded escape sequence is provided in the event that the programmed sequence is lost. It is
Appendix F lists the hexadecimal codes for the ASCII character set.

Each device port saves the output of a server to a FIFO buffer. Each buffer can store up to 64K of data, giving approximately 100 text pages. However, the actual amount of pages may vary according to the data. The user must be in monitor mode to view or clear the data stored in the buffer.
