I am sending the following sequence from Forth:

$9a emit 36 emit $80 emit

in a loop, and I am seeing:

0000000 c000 0000 0000 0000 00c0 0000 0000 c000
0000010 0000 0000 0000 00c0 0000 0000 c000 0000
0000020 0000 0000 00c0 0000 0000 c000 0000 0000
0000030 0000 00c0 0000 0000 c000 0000 0000 0000
0000040 00c0 0000 0000 c000 0000 0000 0000 00c0

directly out of port /dev/ttyUSB1, either by cat'ing to a file and dumping it, or some terminal program ..
However, sometimes it is ok ... and I get the right data.

Is there some problem with the timing at 460800 baud? It only seems a problem after sending an 8-bit value ..
