USART module options

Dear all,
I am having problems in sending serial data from my computer to PIC. Previously my program has no problem in sending the serial data via RS232 comm port. I used 18F1320 before this.
But lately, by using the same program and interface (swordfish) on a 18F2525, the serial data transmission stream ran into errors. I am lost in troubleshooting this. But as I look closer into the USART module, I noticed there are two options which I did not set, ie taking the default values set by the compiler.
There is this option for BRGH16 which I didn't set. I know that the 18F2525 has EUSART module. I let the option as it be, which is false. What does this option do? Can anyone explain.

Thanks

Regards,
Liak

liak you will find this post very usefull, look at post number 6, it has a link to Mister E picmulticalc program, it is a real must have tool and will help with many of the modules in a PIC.

Dear Doj,
Thanks for the info and link.

Shame on me. Should have found the thread by the search. But I find php search very broad and not specific.
Anyway thanks. I have sort of found the root of the problem. I will put it in another thread. It's totally unrelated however to the USART transfer.
The module works again now. I am glad it does again.

I nearly lost confidence in myself to program PIC and SF(nearly!!).

Liak
