So I have battled my way through various forum posts and sites around the internet, and I think I have whittled my issue down to something weird in VirtualBox. Basically, I am trying to pass a serial port into a VM for the purposes of running a fax modem. The modem appears on the FreeBSD host as /dev/cuau0, and I can use Minicom to open it and perform various AT commands at the host level. So, I have set a Windows 2012 VM to put the port as Com1 using the Serial Device /dev/cuau0. The problem is, communication is highly erratic inside the Guest, most characters not coming or going correctly, even under a simple HyperTerminal session. It is almost like the CTS pin is permanently active but the actual device is not really ready for data.
Is this a known issue? Using VirtualBox 4.3.18_OSE on FreeBSD 9.2 Apparently the users and Oracle are pointing the finger at the oh-so-highly-customized-we-dont-know-what-they-did-to-it FreeBSD version of virtualbox, and will no lift a finger to help diagnose the issue. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-emulation To unsubscribe, send any mail to "[email protected]"
