Appendix D Sample Programs
D.1
Sample Terminal Programs
The following program can be used to interact directly from a PC's keyboard with
the Micro488/EX. Hardware handshaking is accomplished directly to the 8250 UART
in the PC as Basic does not support the handshaking process. The program initalizes
the Micro488/EX to…
Use only CR for the serial output terminator.
Set a time out value of 10 seconds
Disable the ID character
Disable Error Reporting
Define a special error reporting macro which re-installs itself at execution
Installs the Error Reporting macro to execute on an error.
From then on, any keys which are typed at the keyboard are printed to the PC's
screen and set out the serial port to the Micro488/EX. Any data returned from the
Micro488/EX is printed to the PC's screen. Errors are automatically reported and
cleared.
