The answer is in your previous mail:

COM1 is for windows, /dev/ttyUSB0 is for linux (and can be something
else for another unixes). Of course it can be COM2, COM3, COM4 or
/dev/ttyUSB1, /dev/ttyUSB2 etc. Check your OS documentation.

Try to connect to your device with other program (minicom on linux,
teraterm or hyperterminal on windows) first so you know which device to use.
