I own a chromebook (ACER C720) that I run Elementary OS on, based on ubuntu.
I used the exact same method as described here and I can use both gtkterm as well as putty to connect to the Micromite, and also the Maximite.

The only difference with he system you describe is that I have removed Chrome OS, and have reflashed the BIOS.

Another thing I can think of is there may somewhere be a conflict with rights. I did not run into this since all modifications I make in the Ubuntu environment always start with a "sudo su".....
That is a habit after working with Puppy Linux, where you are root unless specified otherwise, and you simply get used to that.

I can confirm that the chromebook function keys give different keycodes, and you have to use the CTRL-Q/CTRL-T keys to work with the editor build in into the Micromite.

Regards,

Volhout

GFXterm now works!

Using the info here: Set Up The Serial Port In Wine

I added

[Hardware\\Devicemap\\Serialcomm] 1231984861
"Serial0"="COM1"

to ~/.wine/system.reg

The serial port is found and GFXterm works.

MicromiteCons also now finds the port, but it still doesn't talk to the Micromite.

Hi SteveA
If MicromiteCons sees the port, it should connect. Try with different baud rate, or share a snapshot.
Thanks

The baud rate is set to 38400, which works for the other programs.

I've attached a screenshot for you.

Yes, all the programs show two ports.

COM1 for the MM with serial to usb adaptor.
COM5 for the MM+.

I can click on connect and disconnect and your program responds, the boxes change between red and green, and a message at the bottom of the window confirms the connection etc.

But, if I type a 'short command' list or memory for example, and click on 'send' nothing happens. The TX/RX counts don't increase, and I don't even get any garbage in the console window.

I now have MicromiteCons working, see the screenshot below:

It wouldn't run on Wine v1.6.2, but it will under v3.0.

To update wine in Ubuntu use:

sudo dpkg --add-architecture i386
sudo apt-add-repository 'https://dl.winehq.org/wine-builds/ubuntu/'
wget https://dl.winehq.org/wine-builds/Release.key && sudo apt-key add Release.key
sudo apt update && sudo apt install winehq-stable
