PhoenixBIOS 4.0 Release 6.0, BIOS version SIQ.01.11<BR /><BR />2. Plug'n'Play OS option = YES<BR /><BR />3. Integrated I/O Ports (Parallel, Serial A, Serial B) = Auto<BR /><BR />4. Security &gt;Hardware Protection / Integrated Data Communication Ports (Parallel, Serial A, Serial B) = Locked<BR /><BR />5. Obvious solution: unlock Serial A<BR /><BR />Thank you all for pointing out that the problem was in BIOS.
