[Qemu-devel] serial control DTR/DSR RTS/CTS

[Qemu-devel] serial control DTR/DSR RTS/CTS

[Drlik Zbynek]

Hello.
My external device is connected with serial port and use hardware flow 
control - it can switch beetwen DTR/DSR or RTS/CTS. I have instaled 
winxp and win98 for multiplatform testing in qemu but my aplication - if 
i wont to communicate must by set to "no flow control". In that case it 
could by read from device without lost data, write isn't funcional - 
much data lost.
When I set up some control - state of DTR or RTS are still down and 
communication isn't allowed.
Qemu run under linux. When I run application in normaly installed 
windows without qemu, the application run perfectly with any of that 
conntrols.
Is there any possibility to correct this?
Thanks. Drlik Zbynek.

It seems that it only set dtr, rts to always on but still doesn't 
reflect state on real port - now I can put hw flow control ON but the 
data is still loosing and it is not possible to write to device
