22.4.3 Flag operation in program controlled communication
Program controlled communication provides for half duplex communication, i.e. communication is possible in
both directions, but not simultaneously. Sending can be controlled by the "transmission done" flag. Reception
can be controlled by the "reception done" flag or by directly evaluating the receive buffer.
The flags are special internal relays which turn to TRUE or to FALSE under specific conditions. They can be
evaluated using special functions or system variables.
