[PATCH 1/2] xyz-modem: Wait infinitely for initial y-modem packet

[Pali Rohár]

Now when command loady can be aborted / cancelled by CTRL+C, change wait
timeout for initial packet to infinite. This would allow user to not be
hurry when locating file which want to send. Commands loadb and loads
already waits infinitely too.
