Windows error: no module named fcntl

Fasta module core.py used "import fcntl" (for non-blocking read?), and can't be used in py 3.8.8 under win10 x64. It seems fcntl is for linux only? I searched pypl and can't find fcntl module, pip also doesn't work. fasta should work in windows according to the description, then what's my problem? Any solution for me to fix this?
Thanks in advance!
