I want to thank you SO MUCH for all your help. Here are my issues
that I overcame (sanity check):
1. Why did we have to use 0x1007, instead of 0x10007 that our grep
command returns?
2. PySerial works beautifully. Thank you for the suggestion. What I
had to do was add this to the PySerial source root in serialpostix.py,
after the import termios:
termios.B921600 = 0x1007
because PySerial looks for the actual baud rate in termios (via
getattr()) which does not exist. PySerial actually defines the
following baud rates, but termios does not handle it:
#default values, may be overriden in subclasses that do not
support all values
BAUDRATES =
(50,75,110,134,150,200,300,600,1200,1800,2400,4800,9600,
19200,38400,57600,115200,230400,460800,500000,576000,921600,
1000000,1152000,1500000,2000000,2500000,3000000,3500000,4000000)
... so now I can pass 921600 as a parameter to PySerial! :)
So my next question is - I would like to contribute to the python
source tree by updating termios.h to handle the higher baud rates by
default. Is this a good opportunity for me to submit a patch? I've
never done this before but have always been interested in doing so.
Thanks again!
Blaine
