I ended up figuring out a way to do this... using socat. For qemu, I just provide option -terminal pty and qemu will print the pty it has opened. In my case it happened to be /dev/pts/6 So I had a real serial device that wanted to talk to a program in the virtual DOS machine on /dev/ttyUSB1 So I came up with a socat command that would connect them together: socat /dev/ttyUSB1,raw,cs8,echo=0 /dev/pts/6,raw,cs8,echo=0 The tricky part for me (since I had never used socat) was turning off all the echoing and editing it wanted to do. The only problem is that the app I'm using on the external device wants to see DSR asserted. I had to make a special adapter that looped back DTR to DSR. (anyone know a Linux utility I can use to turn on DTR and leave it on?) -- John. _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
