Serial connection via ASCII driver

Principles
4.1
The received data is received byte for byte and stored in the receive buffer�
All PtP CPs with ASCII protocol driver can be used for serial communication� In
that case, however, the transmitting and receiving function blocks used in FB49
have to be adapted accordingly�
The communication was tested with a CPU 414-2DP, a CP 440 and an RS-485/
RS-232 interface converter�
