CH340G not working with all serial terminals

This is strange. Have my ESP-01 up and running. Termite terminal works just fine, Arduino IDE terminal works just fine. Teraterm, Miniterm and PlatformIO integrated terminal shows nothing in my windows 10 computer. Driver issue with CH340G chip? Another serial adapter using PL2303TA works like a charm. Firmware upload works, but serial terminal in some cases does not. Any ideas?
