the trick of every data line is; it has to me matched to it's impedance,
at least at the receiving end, other way it is ringing. Every pair of
conductor becomes transmission line as soon it's length exceeds " the
length of the rise time" of the signal which is traveling on it.

My 2c - RS232 is extensively used in data centres over cat5 with network kit
for out of band management via serial consoles, usually 9600 baud.
I've done this many times via (multiple) patching panels/frames easily over 100ft,
ribbon/rollover then cat6 but also cat5. This kit tends to be reliable and usually well
grounded though. Well, and "compliant".
