Hi
I am using vxworks 6.6 workbench 3.0.
our bsp supports 2 serial port but v need 4 serial ports to b enabled
I made the following changes in the BSP

N_UART_CHANNEL --4 in pc.h file.
In sysSerial.c I made entry for all the four ports .

Note:
I use the same procedure for vxworks 6.4..Its working fine.
Thanks in Advance

Regards,
Papi
