Wo there. If I am not mistaken, there is no -12 Volts provided by the Tool Box
power supply (gee, and Zorro  II  requires it). It would be highly unlikely to
get an RS-232 serial connection working (which outputs + and - 12 Volts) with-
out one of the required voltages.

I have heard of someone  hacking  a  more appropriate power supply into a Tool
Box but be aware that if  not  done  carefully, this can cause a great deal of
damage.

If I am mistaken (about the missing voltage) I am sure someone will correct me
(grin)
