While cu(1) can talk to the modem without issue, ppp(8) just hangs. Setting ctsrts to false in ppp(8) w= orks 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: on=20 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
