I have a Micromite Plus MMBasic Ver 4.7 Beta 37

I am using a serial ttl input to the computer, I know the serial cable works perfectly because I have tried it with several other items.

Upon plugging the Micromite into the computer with the usb cable (to give it power)

I use the tx/rx cables on the ttl converter on Micromite Plus pins 6 and 58 and it works good apart from I cannot break into the demo loop to type anything

Everytimne I press Control C nothing happens, I have tried it on Termite terminal program and a few others including RealTerm but still nothing happens

Well apart from the test loop saying (and it just keeps looping

Any idea how I can break into the loop?

----------------------------------

This is a simple test loop
(press Ctrl-C to exit)

Your MicroMite Module
has now been on for
00:00:13

Hi Lewis,

First things first, make sure you have Tx and Rx from the USB-to-Serial module connected the correct way round on the E64 module. If you're not sure, just quickly swap them around to see if this works (crude, but quick; and no damage caused)

If this is fine, but you're still having problems then try loading the USB driver for the E64 and then simply use the direct USB console from TeraTerm (or equivalent).

Hope you fix it ok - if not then drop it in the post and I will gladly take a look for you . . . .

Maybe the break key was disabled at some point by running:
OPTION BREAK 0
To see your settings try running:
OPTION LIST

If this is the case then
OPTION BREAK 3
Should restore things to normal

You may need to restart for this to take effect

I believe the issue is that he can't get to the command prompt in the first place!

I hope as well as tx/rx that GND is connected (and no other).

Maybe I missed something? MMBasic manual p.16:

Quote Resetting MMBasic
MMBasic can be reset to its original configuration using either one of two methods:
* The chip can be reprogrammed with the Micromite firmware using a PIC32 programmer.
* Sending a stream of exclamation marks (!) to the console Rx pin at 34800 baud at startup. If 30 of these characters are received in the first two seconds the Micromite will reset itself. This can be accomplished by simply setting the terminal emulator to 38400 baud and holding down the exclamation key while powering up the Micromite (on most keyboards this requires holding down shift and the number one key). If the reset was successful the message "MMBasic reset completed" will display on the console.
Either method will result in the program memory and saved variables being completely erased and all options (security PIN, console baud rate, etc) will be reset to their initial defaults.

... or a hard reset if the AUTORUN is OFF.

Regards
Michael
