Port B (&H231) of the input/output chip carries a signal that provides
information about the state of charge. The mentioned I/O port has got a
fixed address and can not be reconfigured. The interface card C1230S
needs tree I/O port memory ranges: &H220-&H221, &H230-&H231,
&H240-&H241. Take care about the configuration of the PC, to avoid
overlapping with other PC cards.

The battery charger on the multi-function board can take up the following
states:
Fast charging When the operating voltage has been switched on, the charger goes into
the fast charging state if a battery is connected. The battery is charged with
a constant current of about 200-800mA, depending on the battery type.
Bit 7 of port B at address 231H is 0.
Battery not connected The charger recognises whether or not the battery is connected. If there is
no battery connection, bit 7 of port B at address 231H is set.
Fast charging completed If the charging has been ended by the charging controller, bit 7 of port B at
address 231H alternates between 0 and 1 with a period of 250 ms.
Waiting
In this state the charging controller waits for the presence of a valid battery
voltage. Only then does the quick charging continue. Bit 7 of port B at
address 231H alternates between 0 and 1 with a period of 1.5 seconds and
a mark-space ratio of 1 to 11.
