Just adding myself to the list of people disappointed that this does not work. It's very limiting to only be able to communicate with serial devices using strings. Hopefully either this gets resolved or Unity creates their own Serial system

THIS NEEDS TO BE SOLVED! IT'S BEEN YEARS! This is unacceptable

It is import for developers. I am developing 3D printer software. I must get the data from firmware of 3d printer, so i can send g-code rightly.
No received data, the function of sending g-code must not be done !

A year later and no response? Not even to explain why it can't be fixed? One word -- "Sad!"

April 2017, Unity 5.5, issue still exists. System.IO.SerialPort does seem more like a Microsoft module than a Unity one, but if that's the case, just elevate it to M$ to deal with, don't leave it hanging here in a "we might care some day but we don't now" state.

HI,
please fix it, it's a big pb for all serial connection system when we can't have "BytesToRead" Information. At best the system remains on hold, at worst it crashes.
Best regards,
David.

I would also like to see the SerialPort class more fully implemented. All the polling read functions, plus the readData event handler. For me, it seems the only way to get data into Unity from external sources is through the serial port. Please update this ASAP!

This should be fixed, imo, programming stuff with the arduino would be so much cleaner without the needed hacks, and implementation-forced synchronous red timeouts :(
