Unless it is very strangely configured, it sends ASCII characters.  The
ASCII code for '0' is 0x30 and the ASCII code for '9' is 0x39.

I am trying to send data characters 0-9, but don't quite

On a RS-232 line, zero bits are + voltage (typically 5 to 12V) and one
bits are -voltage (typically -5 to -12V).  Each bit stays at the
designated voltage for the duration of 1/baud rate, then the next bit is
sent immediately.  When no data is being sent, the line idles at -
voltage.  Before each character of data is sent, a 'start bit' of one bit
duration of + voltage is sent.  The data comes out LSB first.  After the
last bit, the line stays at - voltage for at least one bit time (the
'stop bit').

So if you type '1', which is ASCII 0x31 or 0110001 binary, the RS-232
signal would be:
+-+++--+-
S1000110K
time -->
which would look like -_---__-_ on an oscilloscope (with no gaps).  Set
the scope to trigger on a rising edge and it should catch the start of
the start bit.

S = start bit, K = stop bit.  After the sequence, the line may stay at -
voltage if there is nothing more to send, or a new start bit and
character may immediately follow.

I need to write math using word.  I need to write integrals and
differential equations and the normal math stuff.  But I do not know how to
find the symbol set in word.  Does anyone know how to get into the format
for writing the equations?

Click on Insert, then Object, then from the Create New tab select
"Microsoft Equation 3.0". You are now in the equation editor and can build
the equation. You need to have selected equation editing when you
installed Word.
