I've just posted a note describing the following on the qemu-discuss list
at opensolaris.org; So apologies if you have to read of it twice.
I'll repeat here my thanks to those involved in making QEMU available.
It's proving to be very useful.
Attached is a patch which enables the serial code for connecting to Unix
tty serial ports on a Solaris host. It's really nothing more than a
bit of tinkering with "#if" statements, and a bit of reordering some
code, all of which should continue to work on the related Linux hosts.
I've verified that it works well enough to support hotsync of a Palm
PDA with a Windows guest hosted on Solaris-10U3_x86 (32bit).
The patch is made against a tarball currently on the opensolaris.org
QEMU downloads area, which is based on an SVN snapshot dated 2007/06/12
(vl.c was dated 10-June-2007). Please do let me know if things in vl.c
have diverged enough to make integrating the patch inconvenient, and
I'll try again after the dust has settled.
Regards,
Marion
