I'm using Device::SerialPort as well. In fact, I think I cribbed the
original code from you. I'm happy to share it, if you'd like to look at it.
I was wrong before -- I'm not explicitly setting raw mode. But a quick
glance at the sources indicates that the default for a new
Device::SerialPort is raw.
I really don't think chr() is needed.
I'm just doing $port->write($cmd . "\r\n"), followed by $port->write_drain;
