PS2PRO KEY OVERRIDE OVERVIEW

The PS2PRO is a small adapter which converts a standard PC keyboard into an RS232 output device. The original version (PS2ADPT) is not user programmable, meaning that the RS232 output characters are preconfigured during manufacture to match the character printed on each keyboard key (for all ASCII keys). PS2PRO adds the feature of user-programmability.
PS2PRO can be programmed to output user-defined strings so that the specified keyboard keys output custom strings instead of their standard, default characters printed on the key. It provides for up to 16 programmable keys, and each associated output string can be from 0 to 6 characters long, so pressing one key can generate an output of "Hello!". Strings are created and associated with a keyboard key, then downloaded to the PS2PRO all from within this program. When those keys are then pressed, PS2PRO outputs the user's custom strings instead of the default factory programmed characters. These settings are nonvolatile so they remain in effect indefinitely with or without power applied -- until the string is altered or removed by the user. If removed, the key output reverts to the factory default character output.
Custom strings can be defined for any of the keys in the left portion of a standard 102-key keyboard. That is, any key above, below or to the left of the large ENTER key including the F1 thru F12 Function keys (and the large ENTER key itself). So the numeric keypad keys, arrow keys, PageUP/Down, Insert, Delete, Print Screen keys are excluded. Not only can your output strings include standard printable ASCII characters, but can include non-printable 'control characters', or 8-bit characters which like beyond the range of the standard ASCII set.
