providedthat allowsyouto press and holdthe CTRL keywhile pressing
other keys when you want to do a series of control functions.
— The keyboard maps indicate which keyboards use the CTRL key as
described here.
Case usually does not matter. When you see ESC a, for example, you can type
A or a. However, If you see an uppercase letter on the keyboard map translation,
you must type the uppercase letter.
Note: In a few instances the lowercase letter must be used.

Erase EOF) is mapped for the following functions:
•
The Response Time Monitor (RTM)function
• New Extension Mode functions
• X.21/X.25 functions
• Connection Menu request
