Since then I've re-used it in other serial based applications - once you get past the learning curve of how things fit together it is relatively easy (I guess like most things). I prefer it now because it reduces external dependencies in a project. > Seems like there are virtually no posts describing solutions using > serial... > Here is a unit showing how to open, read and write (blocking) using the serial unit: https://github.com/ccrause/debugwire-gdb-bridge/blob/master/serialutils.pas Unfortunately there is other code for sending a break command and setting custom baud rates which makes it appear more complicated than it should be.
