COM Port is closed

[kensoni]

I am using the trial Advance Serial Data Logger.
I have a thermal printer using serial port and normally work.

When I install ASDL success and I configuration Serial Port, I see message "COM3 is closed."
Can you give me how to configuration or what must I do.

Thanks for your help.

Hello,

If the COM port is already used for a printer, our software cannot connect to it. You may try the "Spy" mode, but I'm not sure.

When I enable spy mode, a blue screen of death appeared. I had to reboot a few times. But I still get the same message.

After I can open soft, I see message "Starting the program" and no more works.
Although I changed the printer's configuration to let COM be free and then started the software.

Unfortunately, our software cannot help in the Spy mode.

Is it possible you can use a special monitor cable?

But in this case, you need two COM ports on your computer (one for a printer and another for captured data).

So, if I remove printer and connect ASDL to COM, reconnect printer? Do this work for me?

Sorry, but I cannot answer precisely. It is necessary to try.
