No - TX and RX and obviously ground. Those are the only connections on the

High baud rate and no hardware handshaking, though 4m is not long for
RS232. I'd suggest a good quality screened cable. The mic cable
suggested by another poster should do the trick. Connect the screen to
the plug body at the PC end.

That's a good idea even if it's also connected to pin 5?

Its better to keep signal ground and screen separate... so generally I
use a core in a screened cable for signal ground, and save the screen
for its intended purpose.
