It doesn't work here:

../../../tools/runtest -q -P wine -T ../../.. -M kernel32.dll -p kernel32_test.exe.so comm.c && touch comm.ok
comm.c:860: Test failed: WaitCommEvent failed with a timeout
comm.c:881: Test failed: WaitCommEvent error 997
comm.c:882: Test failed: WaitCommEvent: expected EV_TXEMPTY, got 0
comm.c:887: Test failed: WaitCommEvent used 1003 ms for waiting
comm.c:2226: Tests skipped: interactive tests (set WINETEST_INTERACTIVE=1)
make: *** [comm.ok] Error 4
