receiving printable chars and escape codes on serial port

[skinnedknuckles]

I am trying to read data transmitted by a device across a serial port.  When I collect the data with PuTTY it contains escape codes and ascii strings.  But when I try to collect the same data with ComRd() or ComRdTerm(), only the escape codes are collected and the ascii strings seem to vanish.  Any idea why?

The first thing that comes me in mind is a mistake of mine from several years ago: I thought what was coming from serial port as C strings, but because there were several binary zeroes embedded (the terminator for C strings) so I missed all the chars already present in the buffer following the first binary zero.
Looking at the real buffer content in the IDE took few seconds.
