Re: [mh] Problems creating USB-Serial Port

[David N. <dno...@ya...>]

I don't understand why you are using the "unpack" function on the data 
before you send it.  This converts a byte string into a an ascii 
representation of that string.  Does the device expect 5 raw bytes (0xFE, 
0x04, 0x01, 0xBE, 0xD2) or 10 ascii characters "fe0401bed2"?
