The OCM-3 Utilities software provided by Milltronics uses XON/XOFF to ensure
communication reliability. The software is written to be executed on an IBM PC
compatible computer.
The standard keyboard emulates the OCM-3 programmer. Pressing the keys
corresponding to those displayed on the programmer will activate the same function
(see Start Up\Keypad). In addition, special functions are provided using the 'w' and 'v'
keys found on keyboard.
For additional information, refer to the 'README.DOC' file provided on the disk.
