Parallel Enable Logic Command

This command allows the Caretaker Plus to recognize when a computer that is connected to a parallel port on the Caretaker Plus is turned off so that the Caretaker Plus will not accept data from the PC. The factory default is to enable parallel enable logic. When this feature is enabled, the Caretaker Plus requires the INIT line to be high and the SELECT line to be low before receiving any data from the port. If a character other than Y or N is used no action is taken.

Initialization String Command

This command is used to change the initialization string. Enabling of the initialization string occurs when a valid string is entered. Disabling of the string is done by entering a string with the first character set to ASCII 00 (NULL). To enter the characters of the string, you type the ASCII number of each character in hexadecimal followed by an H without commas or spaces in between. Note that NULL serves as a terminator to the initialization string, so it will not be printed along with the string, and any characters following a NULL will be ignored.

Command syntax is: !@issssssss

where ssssssss is the new init string. To disable the string the first char must be 00. Examples:

To enter the string <ESC>E .. . . · · · · · · · !@llBH45H<ENTER> To disable the string .... · · · · · · · · · · · . . . !@I<ENTER>
