Handling Serial Port with script - Tera Term application

Recommended Posts

Sebastien

Hello,

I would like to control a device connected to my PC over a serial cable.

I'm really a newbies in Auto-It and I managed to get a hyperterminal-like program (in this case Tera Term) launched, the serial port configured and opened.

I see the character strings coming out of the serial port, but I don't know how to catch them - and how to send commands on the port.

I would like to:

- check some information on the character flow sent by my device (like Revision number of the firmware, MAC address, IP address, etc...). Can I store these information in variables?

- send commands after the prompt is recognized

Can I do this over an Auto-It script controlling the hyperterminal software or should I create my own GUI with direct support of the serial port (over an external API maybe...)?

Any hint is welcome.

Thanks.

Hello Sebastien,

I've been working for a long time with AutoIt and Tera Term and I can tell you this:

To send commands to Tera Term you will need to use

ControlSend ("Tera Term", "", "", "command you wish to send")

take a look at this command and keep in mind the following:

- you need to use an empty control ""

- you need to be sure that Tera Term window is active at the moment when the command is sent

- you need to be sure that the title will match the one in ControlSend

To get the text from Tera Term - activate the "log" ability and just simply read the log file.

Feel free to ask anything and I'll help.
