freebsd stable - Mar 2005 - SIIG Multiport Card

Hello,

            I am trying to us a SIIG 4 port Multi-port card on FreeBSD 5.3,
and I am having issues with the baud rate.

The kernel finds the four ports, and I can open them, but I am unable to
change the Baud Rate. It is stuck at 115,200.

 

I have this in my kernel config.

 

device  pcu

device sio

 

Thanks

Here is my DMSG boot info.

Thanks to Peter Wemm for solving the final step in getting the SIIG
4-port card to work. You must reset its clock frequency back to a
normal speed as follows:

Edit /sys/dev/puc/pucdata.c

Find the first instance of "Oxford Semiconductor OX16PCI954 UARTs".

Change the four COM_FREQ entries to COM_FREQ * 10

Recompile. Watch all the ports magically begin to work.
