You need to escape quote characters inside your string:

int main() {
    system ("start C:\\PROGRA~2\\BEL\\Realterm\\realterm.exe FIRST=1 SENDSTR= \"B0 P3\" ");
}

In c++ 11 you can also use string literal R"(...)" if you don't want to escape characters:

int main() {
    system ( R"(start C:\PROGRA~2\BEL\Realterm\realterm.exe FIRST=1 SENDSTR= "B0 P3")" );
}
