Changing baudrate.

Hi.
I have bascom 2.0.8.1. and working with Arduino Mega with ATMEGA2560

I need to change baudrate runtime.

I start with config of the Com2;
Config Com2 = 19200 , Synchrone = 0 , Parity = None , Stopbits = 1 , Databits = 8 , Clockpol = 0
Open "com2:" For Binary As #2

Later in the program I need to change this to 38.400 baud.
Have tried;
Baud2=38400
Baud #2,38400
But none work.
Some help please?
regards svein

(BASCOM-AVR version : 2.0.8.1 )

As Config ComX ... is referred to as re-usable in the help file, did you actually try that?

Yep.
ried a new config with the new baudrate, but when compiling I get;
"Com port already open"

Then I tried a Close #2 before config, but same result.

should be Baud1=38400 for the second uart. baud works on the first uart. I know,it is confusing.
Using # should work too.
you show just some fragments, you should show some more complete code that includes the $regfile

try with a terminal emulator if it work or not.

also a CONFIG can be used multiple times as MWS suggest but not the OPEN statement. OPEN and CLOSE multiple dynamic use is for file handling. So use the OPEN just once. But config COM can be used twice or more. If not show the code.
