IDE Serial monitor panel

Hi All:

I normally use two serial monitors, on two ESP32 serial ports.
Today, after changing workspace, I tried to do it but got this message:
“No serial monitors are available to start monitoring a port. Only 3 can be opened at one time.”
and shows only one serial monitor.

What have done wrong?
Any help will be well come.

I’m not familiar with this issue specifically however I wonder if a full OS restart would fix your issue?

As a side note, I have very good experience with a third party serial terminal program called Cool Term (free), and I use it instead of the Platformio monitor. It’s available on Mac and Windows and is actively supported.

I have been looking for a good serial terminal. Was considering IO Ninja but I couldn’t even demo it without dishing out $35. CoolTerm looks quite good compared to what I’ve been using. Thanks!

The support forum is here. The developer is very responsible.
