Yes, it might be considered a bug. But for a lot of these usb-serial drivers, they were reverse engineered by looking at the data streams that were sent to the device from other operating systems. So they tend to reset the line settings each time in order to get to a known state. For real programs, this doesn't make any difference (minicom, kermit, etc.), so no one has taken the time to try to fix them up. Hope this helps, greg k-h Using Tomcat but need to do more?
