Thanks to Greg and Tyler for suggestions on how to essentially allow
bi-directional communications directly to a Dectalk Express while Speakup is
active. Unfortunately, I still am not having success.
For others who may be reading this, I am specifically trying to allow Windows
XP that I have running with VMWare on my Debian box with Speakup compiled into
the kernel to access /dev/ttyS0 which is currently locked by Speakup.
For VMWare configuration reasons, I can't seam to use /dev/synth, and although
I can send data to /proc/speakup/direct_synth, I can not receive data (such as
indexing info back through that method). At this point it would really seam
that I need to be able to use /dev/ttyS0 even while locked by speakup.
I tried Tyler's suggestion of executing:
setserial /dev/ttyS0 uart 16550a
And, although the command executed fine, it didn't seam to make a
difference. Have you had success with this? If so, at what point do you
run setserial? Prior to running vmplayer or after Windows is up?
If anyone has thoughts on how to get this working that would be much
appreciated. Even if you haven't played with VMWare, the general problem is
just being able to echo (and receive) data to the serial port in use by
BTW: I plan on writing a HowTo on my experiences of getting VMWare working
with Debian plus a successful unattended instalation of Windows XP.
Thanks for the help
