For PLC Link, the communication format and baud rate settings are fixed:
Data length: 8 bits
Parity: Odd
Stop bit: 1 bit
End code: CR
Start code: No STX
Other system register settings will be ignored.

CPU types C30 and C60 offer a USB port. To use this port, COM port 2 must be set to "Internal USB port". In this
case, COM port 2 of the communication cassette cannot be used. Vice versa, if COM port 2 has been set to
"Communication cassette", the USB port cannot be used.
For C14, COM port 2 is set to "Communication cassette". This setting is fixed.
