/dev/ttyS1 on openrd
today I tried to use the serial port on my openrd-base (the rs232, not
the one with the mini-usb connector).
After half an hour trying to understand why my ttl level shifter
didn't work, I tried on an other computer, and everything went fine =)
This thread  has a patch to enable UART1 by disabling the SDIO with
a boot parameter; it would be nice if it could be ported to debian
