Hi All,
 
 
My gumstix has 2 serial ports, one is for GPS receiver, the other one is for Maxstream receiving data from somewhere else, and we use bluetooth to upload and download the program. To do this, we comment "::respwan:/sbin/getty -L ttyS0 115200 vt100". However, if there is something wrong with bluetooth we are able to connect the console through the serial port, thus we are not able to connect the gumstix at all. 
 
Any suggestion about this? I appreciate it.
Thanks
