A suitable terminal program for communicating with a PC is:
Terminal.EXE (included with MS-Windows).
If the waterbath is put into remote control mode via the menu level,
the display will read "OFF" = REMOTE STOP. (see page 29).
The waterbath is now operated via the computer.
In general, the computer (master) sends commands to the
waterbath(slave). The waterbath sends data (including error
messages) only when the computer asks for it.
A transfer sequence consists of:
 command
 space ; Hex: 20)
 parameter (the character separating decimals in a
group is the period)
 end of file (; Hex: 0D)
