https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229712 Bug ID: 229712 Summary: no cts/rts for serial port in bhyve connected to serial port on host Product: Base System Version: 11.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: misc Assignee: bugs@FreeBSD.org Reporter: stb@lassitu.de When trying to run ppp(8) inside a VM against a USB serial port on the host, it appears that CTS/RTS is not handled correctly. While cu(1) can talk to the modem without issue, ppp(8) just hangs. Setting ctsrts to false in ppp(8) works around this. On the host, ppp(8) works fine without disabling ctsrts. The bhyve VM is managed with vm-bhyve, and the USB serial port is exposed to the VM by -lcom2,/dev/cuaU0. The USB serial port is: umodem0 on uhub1 umodem0: <HUAWEI Technology HUAWEI Mobile, class 0/0, rev 2.00/1.02, addr 1> on umodem0: data interface 0, has no CM over data, has no break This is on 11.2-RELEASE with GENERIC. Here's some more detail about the setup: https://lists.freebsd.org/pipermail/freebsd-stable/2018-July/089293.html Right now I don't have a test case better than trying to set up this exact scenario. -- You are receiving this mail because: You are the assignee for the bug.
