VFD Display Baud Rate Settings

I am trying to use a GU112x16G-7003 VFD from Parallax.
I ran the demo programs on a Stamp2 no problem.
Now I am trying to run another display (Same type) on a BS2px and the screen is all junk like a bad baud rate setting.
There is no documentation on changing the baud on the display (J0-J3)
The demo program is using 38.4k baud (Baud = 6)
Do I need to change anything for the px?
Thanks,

I have been looking in the Stamp Manual and missed it.
Also in the Demo Programs it shows lines of code to run the VFD, like ( SEROUT VFD, Baud, [noparse][[/noparse]$1F, $28, $77, $10, $01] ).
I dont see anywhere it explains all the elements of the code.
Thanks for the help.

I had issues with my LCD when I switched to a BS2PX from the BS2, and found this gem.
As to the Serout command.
In the basic manual...
SEROUT {Pin}, {Baud}, [noparse][[/noparse]{commands}]
{Pin} => VFD would be the defined pin that your sending the signal on
{Baud} => from your select and a CONstant defined in your program.
The commands are different based on the LCD,VFD your using, but would/could be defined in your program after reading the VFD manual.
Hope this helps.

I just got back from a meeting at the customer site, and the manual finished downloading.
I saw the Serial information.
The Noritake web site leaves lots to be desired.
I requested the full data sheet and they will send it in 24-48 hours.
I do have enough information to get this part of the rush job done.
Once again thanks for the help evereyone.
