You don't have a header and body, just a bunch of bytes. First things first, you need to identify the header and the body.	[reply]

Yes,you're right. I know I have to identify the header and body, that's why I convert messages in $buffer(binary) into @msg. The question is after I insert 3 bytes into @msg, I don't know how to convert modified message in @msg into the type that can be sent out by syswrite().	[reply]

I doubt it's necessary or even helpful to create `@msg`. And populating it with the hex nibble pairs is particularly backwards. Populating it with the values of each bytes would make more sense if there's any reason to create `@msg` in the first place. `my @msg = unpack('C', $buffer); ...do something to @msg... $buffer = pack('C', @msg);` [download]	[reply] [d/l] [select]
