See EblGetCharKey() in https://svn.code.sf.net/p/edk2/code/trunk/edk2/EmbeddedPkg/Ebl/Main.c The simple, non timeout, version is: gBS->WaitForEvent (1, &gST->ConIn->WaitForKey, &EventIndex); Status = gST->ConIn->ReadKeyStroke (gST->ConIn, &Key); if (EFI_ERROR(Status)) { break; } You need to read the key.
