I don't know if this qualifies as "help" or not, but here goes a
couple ideas:
a) I once had trouble talking to a device, I think it was a Cisco 675,
until I turned _off_ all flow control (hard and soft);
b) maybe you aren't supposed to cross transmit and receive (i.e.,
whatever document you are looking at didn't intend you to).
