That is pretty good analysis of what maybe happening.
I have not noticed the "saver" posts the port baud rate.
It really doesn't matter - the baud rate is a fiction for serial over USB.
it's a software fiction that makes a USB link look like a serial interface.
Even if the baud rate is on borderline of the system ability the
RS232 protocol should be able to control the its data flow.
Nope - there's no XON/XOFF or CTS/RTS kind of flow control.
For "USB emulating serial" (which is the case on both ends of the link) it's not really RS232. So the 115.2 kbps is sort of a bogus number. It's mapped into packets traversing the USB and those packets are sequenced into a 8 kHz slotting system.
Either you have enough buffer on the receiving end, or "stuff happens".
