Hi,
I'm using ubuntu 9.04 on that i'm running ttylinux-i486-9.10( i486 )as a virtual machines .
I have created the virtual machine using KVM-Qemu .
I open the serial port using
fd=open("/dev/ttyS0, O_RDWR | O_NOCTTY | O_NONBLOCK);
I'm compiling this using gcc compiler, it complies with out any warning and also no error while opening the port .
I get error only when I tried to read or write to opened serial port .
i.e write(fd,'c',1)
error I get is " Input/output error " .
regards
Bala
