Serial port on a migrated VM

Hi everyone,

I'm having a problem with a serial port that was working just fine on my 4.1 ESX. After I migrated the VM on the new ESXi 5 host, updated the vmtools and hardware, the serial port is still not working.

I don't seem to have any data going to the VM when I open my putty.

I use a physical port, and strangely, my host is a Dell R720 with 1 physical serial port, but there's 2 serial port that I can chose in vSphere (/dev/char/serial/uart0 and /dev/char/serial/uart0). I tried with both, with and without Yield CPU on poll. But still nothing

Any idea ?
