NOTE on RS-232 Serial Cables
At lower peripheral speeds of up to 9600 baud,serial interfaces can
usually operate over cables up to 50 feet long. Use of special high
quality cable may in some cases allow this limit to be extended to as
much as 150 feet.

At 15-15 meters, you're at the end limit, [@ 9600 baud], for a
"standard" RS-232 cable.
Just keep that in mind when you buy a cable....
