If would be nice if Synwriter could display non-printable characters. For example NotePad++ will show NUL, STX, ETX etc. for ascii values below 32. This certainly makes viewing files containing these values easier. I use Notepad++ specifically for this feature when reading logs files of data transmissions for certain types of equipment that starts the transmission with an STX and end it with an ETX and often the CRC value is a character below ascii 32 and it is nice to see what this is.
Thanks,
