Hello,

I'm currently testing our product with QNX 6.4.1 vs 6.3.2 and have hit a bit of a stumbling block.  We used to use /dev/
ser0 as our first serial device by calling the following command:

devc-ser8250 -C 1024 -e -u0 -c14285714/16 -b9600 0xef600300,0x0

where -u should make the numbering start at 0.  However this is no longer the case in 6.4.1, it seems that even with 
this option we are getting our first serial device at /dev/ser1.

# ls /dev/ser*
/dev/ser1      /dev/ser13     /dev/ser3      /dev/ser7
/dev/ser10     /dev/ser14     /dev/ser4      /dev/ser8
/dev/ser11     /dev/ser15     /dev/ser5      /dev/ser9
/dev/ser12     /dev/ser2      /dev/ser6

Process 258064 (ls) exited status=0.

Is there any way to get the old behavior?

Thanks,
Liam
