appendix B
This appendix shows the supported character sets.
Each character set consists of a series of control characters and displayable characters.
Displayable characters are alphanumeric, symbolic, or graphic characters that can be dis-
played on the screen or printed by a hard copy device. Control characters enable the termi-
nal emulation or the printer to perform specific tasks, such as a line feed or carriage return.
These are acted upon when received from the host or when the emulator is in local mode
and they are entered from the keyboard.
To enter a control character from the keyboard, first find the displayable character equiva-
lent 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 generates a CR code in
local mode.
Some setup options require you to specify one or more control characters. A control char-
acter 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 para-
graph. 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 three-digit numbers immediately preceded
by an underscore character. Values with only two digits must be preceded by a zero. For
example, the decimal value of CR is 13, so this would be entered as _013.
