looping over a string character by character in Verilog

I'm attempting to send a string character by character over a serial port. I have the serial port down, but I don't quite see how to implement a changing index on a string... Ideally, my module...

You may start defining your message array like this:

reg [7:0] message [29:0]

Then you can use simple indexing to access each character.

Moreover I would recommend using a clock and synchronous logic.

Infact, always @* implies a purely combinatorial behaviour: this is usually not recommended, especially in your case which is basically a clock-driven process.
