You should just skip the GernericComm component if you want to
eliminate the TOS_Msg format. Go down to the raw UARTM component.
See that code for changing baud rates and such.
Or, much easier, if you can change your host receiving program, just
add the TOS_Msg header to it. You can use the MIG program to generate
Java classes for your messages, or look at my code bolus for examples
of rolling your own: http://www.etantdonnes.com/Motes/robocode.tar.gz

Yup I understnad that my device will not understand TinyoS packets but
it still communicates 8bits at a time with 1 stop bit and no parity so
the display should display what I want it to (along with some rubbish
generated by the packet header) once I had it working I was going to
then make changes to GenericComm(and lower interfaces) to remove the
header. I read the boomerang sample but I am not using boomerang at the
moment.
I was really looking to find out how to send data to the serial port
using GenericComm and how to alter the baud rate.
Thanks for the help though,
Chris

You need to write a driver for your device. I'm pretty sure that your
device doesn't understand TinyOS formatted packets that GenericComm
sends. There's an article on Moteiv's support site about using UART0
with Boomerang:

I've searched through the archives and can't find a definitive answer to
my question so I am hoping someone here can help.
I'm looking to connect a display up to my mote through the serial ports
that are on the expansion pins and I have two problems,
1. Can I use the genericComm to send to this UART or is it only the USB
port that can use the genericComm?
2. If I can use the genericComm how do i change the baud rate from
57600bps to 9600bps? How do i change the destination address so rather
than going through the USB port it goes through the UART (at the moment
i just use the line
call Send.send( TOS_UART_ADDR,sizeof(IntMsg2),&data)
to send to the UART but that sends over the USB instead of the expansion
UART.
Thanks in advance,
Chris
