It seems the Galaxy S21 is not supported. In the *#0808# menu, only 'MTP' and 'RNDIS + ACM + DM' are shown. When selecting the last option i don't get any data when i run scat using the following command:
jeffrey@lptp-jeffrey:~/projects/scat$ sudo python3 scat.py -t sec -m e333 -u -a 003:002 -i 4

It seems it is properly detecting some interfaces, but no UP/CP data is sent to localhost. I don't think this can be changed by a configuration option, but don't know the modem internals.
handymenny commented
See #27 there isn't much you can do if samsung has "blocked" diag in your firmware
Someone solved enabling "AT 3GPP commands" in developer options, but your mileage may vary
jeffreykog commented
Thanks for your response. Enabling the 3GPP AT commands doesn't seem to help, so i think i'm out of luck with a locked-down modem firmware.

Did you try changing the last parameter from python3 scat.py -t sec -m e333 -u -a 003:002 -i 4 for me -i sometimes works with 1 instead of 4, even though I use a Qualcomm phone, don't know if for Exynos would be the same.
Cainor commented
Same issue. Is it just a Samsung thing?
