Hi,

I am working on the upgrade of a system that prints data directly on a dot matrix printer. I have already designed a parallel port (SPP-> UniDirectional) capture device and grabbed the data. Now all I want to know :

Is there any text/ASCII viewer which would let me find the values(ASCII Codes) of non printable characters on mouseover or whatever, so that I can decipher the printer control commands and filter the data needed through the PIC.
