Subject: fprintf without "\n"
Hi,

I find that fprintf will append a "non printable"character (looks like ASCII #2  STX or #3 ETX) at the end of the string if the string is not terminated with "\n". Is this is the intended behaviour ?

This is a test case:

#include "KMotionDef.h"

main()
{
    FILE *f=fopen("C:\\temp\\test.txt","wt");
    printf("Transmission of %d rows,", 1);
    fclose(f);
}

This particular test appends the ETX character, another more complex examples seems to append the STX.

Thank you, best regards

All printf or fprintf must be terminated with a new line character or the results will be indeterminate.  (A single stream to the PC and KMotionServer is used for printf, fopen, fprint, fclose except with embedded control characters of 0x01, 0x02, 0x03).
