+This decoder should work on all "UART-like" async protocols with one
+start bit (0), 5-9 databits, an (optional) parity bit, and one or more
+stop bits (1), in this order.
+
+It can be run on one signal line (RX or TX) only, or on two lines (RX + TX).
+
+There are various standards for the physical layer specification of the
+signals, including RS232, (TTL) UART, RS485, and others. However, the logic
+level of the respective pins is only relevant when acquiring the data via
+a logic analyzer (you have to select the correct logic analyzer and/or
+the correct place where to probe). Once the data is in digital form and
+matches the "UART" description above, this protocol decoder can work with
+it though, no matter whether the source was on TTL UART levels, or RS232,
+or others.
