Byte 4:
iomode...
The byte 'iomode' contains, broken down into 6 bits, information about the
operating mode of the addressed module. A '1' of the respective bit signalizes the
operating mode possible for this module:

Bits in parameter 'iomode'
Example: At a CAN-CMIO module the value $0F would be replied for
'iomode'. The value for a CAN-CBM-SIO is not defined at the
moment.

Byte2...
See sub command $00.
Byte 3:
switch...
The byte 'switch' replies the number adjusted on the coding switches.
If the module no. filed in the EEPROM has got the value $00 or if the EEPROM
data are not OK, the actual module no. by which the module is addressed during the
initialisation corresponds to this coding switch number.
