https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200445 --- Comment #6 from Matthias Apitz <guru@unixarea.de> --- (In reply to Konstantin Belousov from comment #5) I have not specified hw flow control and I do not know if the USB-serial supports this. As described in the handbook, I added to /etc/ttys a line: cuaU0 "/usr/libexec/getty std.9600" vt102 on secure and after 'kill -HUP 1' on the terminal, login as root is possible and, for example, an 'ls -lR /' works nicely passing the output fine to the VT102; i.e. I do not think, that we have some flow control issue; the only things I have figured out so far are: 1) one can not use /bin/sh as login shell, it will hang on login; 2) you can not open /dev/tty after login; it will hang 3) if you use MUA mutt, and below this the vim to write the mail, mutt will hang too after the end of vim; and a Ctrl-C makes it continue (perhaps for the same reason of hang on /dev/tty open call) what Do you want me to check or change exactly?
