Figure 8 shows the TCLSH screen with the commands being run, the output file is shown below, the CSD is shown. 
To output decimal data, the “d” command could be used, for example:

% puts $com “d”
% gets $com dd

Then the GetCSDPos command would get Decimal data. Notice the gets command follows the puts command and 
just reads the com port to clear it.

Figure 8: GetCSDPos example
