Hi folks.

   I am trying to flash a 16LF648A using a Wisp628. First I use this:

C:\MCHIP\Blink>xwisp.py go uuu

   And I get this:

XWisp 1.08, command line mode
C:\Archivos de Programa\XWisp\serialwin32.py:88: DeprecationWarning: 
integer arg
ument expected, got float
   win32file.SetCommTimeouts(self.hComPort, timeouts)
hardware: Wisp628 1.09 (fast)
target: 16f648a, revision 01 (ID=1101)
OK

Then, if I try to read the program from the chip, I get this:

C:\MCHIP\Blink>xwisp.py read 123
XWisp 1.08, command line mode
C:\Archivos de Programa\XWisp\serialwin32.py:88: DeprecationWarning:

   win32file.SetCommTimeouts(self.hComPort, timeouts)

And that happens with any program I try. This is the code:

It is just something I found on the net and I was using it just to test 
the Wisp628. Any ideas what could be happening?
