Eclipse terminal not monitoring output

[mylenedipenta]

I'm testing an ESP32 DevKitC using the Hello World example program. I can build, flash, and monitor from the command prompt. Now I'm trying to do the same in Eclipse. Build and flash work fine, but the the terminal in Eclipse is blank. I can use a command line to run idf.py -p COM4 monitor and see the output; I've also checked menuconfig for that project and it's running at 115220 bps. But if I set up an Eclipse terminal session using the same settings (plus 8-N-1 ISO-8859-1 encoding), all it shows is a blinking cursor.

Interestingly, if I try to run idf.py monitor at the same time, I get an error saying access denied, so it does appear that Eclipse is taking control of the com port. Any thoughts?

My details
Win 10
ESP-IDF 4.0
Eclipse C/C++ 4.10.0
Eclipse plugin installed (as of yesterday)
