New issue 270 by angry.de...@gmail.com: Adding support for changing default
PN532 UART baud rate.
http://code.google.com/p/libnfc/issues/detail?id=270

What steps will reproduce the problem?
1. Use pn532 in UART mode.
2. Attempt to set UART baud rate to anything other than 115200 baud via the
devicestring baudrate suffix.


What is the expected output? What do you see instead?
I expect to see a change in the baud rate :-)
Instead the baud rate remains fixed at 115200 baud.


What version of the product are you using? On what operating system?
LibNFC 1.7.0, on Arch linux on ARM (raspberry Pi)


Please provide any additional information below.

I have cloned the repository and added some code that does the job for me,
but probably not for all cases. The code will allow changing the UART baud
rate to any rate supported by the PN532 via the standard(?) baud rate
option in the devicestring.
See : http://code.google.com/r/angrydeity-pn532-uart-changes

Note that the repo also contains a small patch to add a 100ms UART timeout
to allow the library to return semi-gracefully if data is lost instead of
hanging on the select() forever.
