WCE 1.20

Italy 0070 once again, sigh ;)

Removed the beeps on errors/resets

RTS now set to +12 volt for powering season

Changed back to answer 6b00 for unknown seca instructions.

----------------------------------------------
Some info:
----------------------------------------------
Cable for Season: use straight pin-to-pin
9 pin computer side, what pin is used for what

pin 1	DCD <- Reset from CAM
pin 2   Receive  <- Data from CAM
pin 3   Transmit -> Data to CAM
pin 4   DTR -> not used, set to -12 V
pin 5   Ground (common ground)
pin 6   DSR <-  not used
pin 7   RTS ->  not used, set to +12 V
pin 8   CTS <-  not used
pin 9   RI <-   not used

----------------------------------------------
The following diagram describes the whole interface:

    At the MAX232, pin 2 delivers
    +10 V and pin 6 delivers -10 V.        (also connected to 74LS07:
                                           pin 7=GND, pin 14=VCC)

=== and || denotes capacitors (4 in total), observe polarity (+ is marked)
