7. Serial interface

The machine has a serial interface according to the standard RS232C. Via this interface
parameters can be adjusted. All received commands are tested for syntax and legal value
range.
Invalid commands and parameters are ignored. An error message is not given in this case.
All commands received over the serial interface are tested for syntax and range; invalid
commands and out of range parameter values are ignored. A warning message is not given in
these cases. However in the case of framing, parity or overrun errors the warning "W__3" is
generated.
The commands are made up of sequences of ASCII characters. Each command starts with "#"
and "!" followed by a 4 character code. The reception of the "#" character indicates the start of
a new command to the machine.
The codes are similar to the parameter names shown in the display.
