Bad news:
It seems that besides doing the PTS protocol with the
card and increasing the speed of the serial port,
Chipdrive controler needs to be informed of the new
serial por speed.
The problem is that the commands for changing the
serial speed are not going to be published by the
manufacturer, so we'll have to conform with a fixed
speed of 9600, event if the driver successfully does
PTS protocol.
The upcoming release 2.0.0-pre5 T=0 module will come
with serial speed fixed to 9600 bps.
I apologize for the inconveniences.
Thanks,
Carlos.
