Initialization strings can be sent at the beginning of the session to ensure that the terminal is in the proper state, or to program special function keys. This is primarily used to program function keys and function key labels with application specific information. The codes is, is1, and is2 are always sent at the beginning of each session. You can specify a sequence to send at the end of the session with DI.
With the VT-100, it is useful to set the numeric keypad to numeric mode (as
opposed to application mode). This is done by sending "ESC>". The new entry is then:
