Connecting to a domain socket requires additional tools like ""socat"" to transform the vbox domain socket to either a PTY or TCP port. It would be nice to be able to redirect a guest's serial port *directly* to a pseudo terminal slave device on UNIX hosts. Basically I would like to do something like: {{{ VBoxManage--uartmode1 /dev/ttyp1 screen /dev/ptyp1 && VBoxManage startvm linux }}} On v 4.1. this fails with Failed to open host device /dev/ttyp1 VERR_RESOURCE_BUSY A forum thread describing this issue: https://forums.virtualbox.org/viewtopic.php?f=2&p=101962 I hope adding this is not too difficult since you already support TTYs. Thanks." enhancement closed uart VirtualBox 4.2.0 worksforme PTY all all
