In general, as long as the data quantity is not too large and you
use Xon/Xoff as flow control, it will be problem free.
Baud rate: 2400, 4800, 9600, 19200 and 38400.
(Programmable by command)
Data format: always 8 data bits, 1 start bit and 1 stop bit.
Parity: always non parity
Handshaking: XON/XOFF as well as CTS/RTS (hardware
flow control).
If you run an application with the bundled printer driver under
Windows and use the serial port, you should check the above
parameters and set the flow control to "Xon/Xoff "or "hardware".
