In what context? Strings are not suitable for synthesis, so I assume this is simulation only code?
Also, strings can only have a positive range, so cannot start at 0 - it must start at 1 or above?
Why bother coverting the char to an integer? why not just use the chars directly?
if (idx < RX_BUF_SIZE) then
case rx_uart_buf(idx) is
when NUL => ParseState <= ST_PARSE_IDLE;
when ' ' => ParseState <= ST_PARSE_ARG1;
end case;
idx := idx + 1;
end if;

I see. Thank you. So it doesn't work in real life? I was planning to accumulate chars from terminal to rx_uart_buf and then parse the string.
