The software may be the same, but the computers, serial ports, and
serial drivers are different. Clearly the packets are getting garbled
in the second case. I can see that the hints are not very useful;
they should be more context-sensitive (since they know what the local
flow control is, and they know that streaming is not in effect).
My first suggestion would be to try a lower speed and/or shorter
packets.
