I also looked at the VM log and I didn't see anything obviously amiss as the VM was coming up. There was an option in the Device Manager (I think) that searches for new hardware (?), but it didn't come up with anything when I tried it. I'm in no way a 'Windows Guy,' so I have no idea whether there's something I need to do in Windows to create the COM1: device node. However, when I went to the Device Manager to look for COM1:, it wasn't there. So I did that, and lo and behold, the VM started up and booted Win XP successfully. I googled 'tty vs cu' and came up with this article, which led me to think that I should try mapping COM1: to the 'cu' aspect of the device instead of the 'tty' aspect. I noticed that when I plug in the USB-to-Serial converter, I actually get two device nodes in /dev : Apr 2011, 18:08 Primary OS: Mac OS X Leopard VBox Version: OSE other Guest OSses: Windows XP (Of course, I can uncheck the 'Enable Serial Port' checkbox and start up successfully, but then I have no way re-enabling the serial port once the VM is up and running. Trying to start up the VM with the USB-to-serial device unplugged doesn't work: it fails with the following messages at the end of the log:Ĭode: Select all Expand view Collapse view 00:00:01.215 ERROR : aRC=NS_ERROR_FAILURE (0x80004005) aIID=, preserve=falseĠ0:00:01.290 Power up failed (vrc=VERR_FILE_NOT_FOUND, rc=NS_ERROR_FAILURE (0X80004005)) The last entry in the log file is '00:00:00.858 Serial#0: emulating 16550A', and nothing that looks like an error indication. (2/2)' and a progress bar that (to my eye) appears to be stuck at about 20%. Then a few seconds later, a notifier pops up over the VirtualBox window, with the caption 'Starting virtual machine. ' dropdown appears in the VM window, with no progress shown in the progress bar. But when I try to start my WinXP VM, the 'Starting virtual machine.

The packet radio applications I intend to run under WinXP want to communicate with the TNC via a COM port, so in VirtualBox's 'Machine->Settings.' dialog, 'Ports' tab, 'Serial Ports' sub-tab, 'Port 1' sub-sub-tab, I select the following: I know that the cable+driver combination work on the host, because I can connect to the TNC using the 'screen' VT100 terminal emulator application, type commands at it, and get good responses back. Peripheral: USB-to-Serial converter cable (using the pl2303 driver) connected to a Tracker2 TNC (packet radio modem).Host: MacBook Pro running OS X 10.5.8 and VirtualBox OSE 4.0.4.I have a similar problem, so bumping the thread and hoping for some response.

Disappointing to see no replies to this post.
