Hello. I've got a box connected to an hardware device through a serial port. This is a real RS-232 on the motherboard, not an USB adapter. From time to time, the serial port will got stuck and stop communicating with the device. This is not a problem with the device, as powering it on and off won't help. Instead rebooting the whole FreeBSD server will solve. This box, however, is running several services, several jails and a couple of bhyve VMs, so rebooting it all is... somewhat troublesome at the least. Is there anything I can try (hopefully a long time from now) to get the serial port back working without a real reboot? bye & Thanks av.
