Configurable buffer size

[MathiasYde]

I'm making a program that needs to send 16K bytes over a COM port but my program freezes due to the default buffer size on Windows (4096 bytes).

I don't see an implementation in this crate to change the buffer size, is it even possible?

In general the internal OS level buffers are usually a fixed size of 4K and so can't be changed. You should instead be copying the data out into a program buffer.
