Character Sets
This appendix shows the supported character sets.Introduction
Each character set consists of a series of control characters and displayable charac- ters. Displayable characters are alphanumeric, symbolic or graphic characters that can be displayed on the screen or printed by a hardcopy device. Control characters enable the terminal emulation or the printer to perform specific tasks, such as a line feed or carriage return. These will be actioned when received from the host or when the emulator is in local mode and they are entered from the keyboard.
Note: When the Display Controls option in the Terminal Settings dialog box is selected, a representation of most control characters received will be displayed on the screen instead of actioned.
To enter a control character from the keyboard, first find the displayable character equivalent by adding 64 to the decimal value of the control character in the relevant character set table. For example, the control character CR (carriage return) has a decimal value of 13. Adding 64 makes 77 which is the decimal value of the displayable character M. When the Ctrl (control) key is held down and Shift + M is pressed, this will generate a CR code in local mode.
Some setup options require you to specify one or more control characters. A control character can be specified by typing ^ to represent the Ctrl key, immediately followed by the displayable character equivalent of the control character as described in the previous paragraph. For example, ^M, represents Ctrl + M, which generates the control character CR.
Another way of specifying control characters is by entering the decimal value of the ASCII character. Decimal values are entered as
