SDK • tinyUSB TX Fifo size

I am having an issue where if I try and write more than 256 bytes through the USB CDC, it seems to drop all characters after writing 256 bytes. I am connecting to the Pico with a WIndows application running at 115200 baud.

I am simply calling the putchar_raw() function in a loop.

I was thinking that it may have to do something with the tinyUSB TX Fifo size (CFG_TUH_CDC_TX_BUFSIZE).

Is there any way to specificy this size in the project configuration (in the CMakefiles.txt for example)?
