Can anyone suggest a way in which I can 'pipe' the console output to a string variable?

Eg. if I want to send the output of an OPTION LIST command to a variable?

I know I can capture it with teraterm or similar but I would like to be able to do it internally in MMBasic.

I was thinking similar.

If we knew where the serial transmit buffer was in memory, we could peek into it immediately after "OPTION LIST"

That would be a really nice feature.

Use MM.INFO(OPTION option). If any options that make sense are missing I'll add them

Thanks Peter,

I was thinking of a more general usage. When I am developing a program, one of the tools I use to debug the program is to intersperse PRINT variable statements at strategic points so I can see what is going wrong

This works fine when connected to a PC - the console output shows these as well as error messages without screwing up the graphics display. In a standalone situation however, this is hard to achieve (I have used the method where I create a log file and dump the progress/error statements into that but it is messy and time consuming).

I was hoping there may be an easy method already available of diverting the console output to either a string/longstring or file for analysis on a temporary basis - a bit like TRACE ON/TRACE OFF (and, in fact this would allow TRACE ON output to be collected for analysis).

Thanks for a great program and all the support you give,
Doug.

A few weeks ago I came across this video (about 20 minutes long) while looking for something else: Realtime debugging using serial decode

Although I've been doing embedded for more than two decades, it talks about an idea that I'd never even thought of: how to extract data from an embedded system without having to resort to pushing stuff to a console.

Sure, the data might not be as convenient as a nicely formatted string on a terminal emulator, but you can get the data out real-time if need be, and for debugging that can be a life saver.

I really don't like pushing videos, but this one was a real gem!

Cheers,
