I downloaded the latest version (V4.69) of TeraTerm from Sourceforge. It's powerful.

The script below sets the title of the terminal window, connects to the MaxiMite and sets the date and time. The macro language can also process screen output from the Maximite which looks interesting.

Try this....

Cut and paste the script below to a file called start-mm.ttl.
Change the number of the com port to the one you use.
Save the file to somewhere easily accessible.

Windows 7 is a pain in the proverbial for this sort of thing. I cannot save the macro file in the same directory as the program. It's good security, but difficult for older programs like this. I suggest saving it on a thumb drive, or any drive except C:. I tried my E: drive and I couldn't save it, but I could on my M: drive. Go figure.

Create a new shortcut, or change the Target properties of the Tera Term icon to "C:\Program Files (x86)\teraterm\ttpmacro.exe" "m:\start-mm.ttl"
Note that it's no longer starting Tera Term, it's starting the Tera Term macro program, which starts Tera Term and executes the commands. You'll have to change the drive letter / location of the macro from m:\ to whereever you saved the script.

Now, when you click on the icon, it opens Tera Term and sets the time and date on the Maximite. Neat.

Here's the script:

Thats a handy tip James

I'm using TeraTerm to talk to my Maxmite, so will try it out.

Great hint James but the macro has an error that causes the time to not be set when first plugged into USB and run. When I enter 'print time$' the clock is zeroed but 'print date$ 'is OK

If you go into TeraTerm and go Control / Macro then select your macro and open it it comes back with error:
Variable Not Initilized
Sendln 'TIME$='"CurTime""M:\

To fix problem change line to following:
Sendln 'TIME$='"CurTime""

Looks like the M:\ may be a typo or error from your editor

Yep - Agree. That's a typo or cut-and-paste error.
Thanks for pointing that out Ray.
Apologies to everyone who was caught by that.
