Dear all, 

Until the installation of FC6 this morning, I have used modem in FC5 
without any problem. But in FC6, the modem does not respond at 
all. Query modem from kppp shows modem detection (even when it is 
turned off!!!), but modem query result remains empty.  That made me 
suspect that ttyS0 is pointing to something else. As is evidenced by 
the output from dmesg, 


Xen virtual console successfully installed as ttyS0 


I have tried not starting the xend daemon at boot time, but that did 
not work. Could any kind soul tell me how can I make my modem work. 
Then I tried putting xencons=off in grub. That prevented xen from grabbing 
ttyS0, but still my modem remains undected. kppp simply says unable to 
detect modem (as well as minicom). 

Could any kind soul please tell me how to use a COM port modem with a Xen 
kernel?

Thanks in advance.
