It probably does have hardware handshaking then, which is a good thing. > Not AFAIK. I had vendor support guy on the line and I was screensharing. His > expectation was everything should be at 115200. What serial interface are you using on the OpenBSD machine? Is it a puc device by any chance? It's possible that the serial port on your OpenBSD machine is actually running at 115200, even though you have it set to 9600. I'm also wondering if it's possible that when the switch is reset, the serial line is going low for long enough to be recognised as a break and confusing misbehaviour that way.
