USB Serial and Serial1 and Serial2 COM Port no function

[sirpete83]

Hallo,
in the past I used another STM32 Arduino core. I had no SPI function. so I switched to this one, seems newer and active in developement. Fine my SPI part is working fine, but I lost the whole Serial functionallity.
I have "BluePille" seems to be original but who knows.. It is STM32F103 using STLINK SWD for Upload.
comport appears and I can connect with the terminal but no data is transmitted. so I tried to use Serial1 and Serial2 but there again no signals on the pin.
I have not tried to switch back to the "old" core but will try this evening, maybe someone has a good hint, what i'm doing wrong.
