In general as long as the data quantity is not too large or you
use Xon/Xoff as flow control, there will be no problem at all.
Baud rate: 2400, 4800, 9600, 19200 and 38400.
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”. However, a parallel connection is HIGHLY
RECOMMENDED for connection to a Windows-based PC for
best performance.
