if you don't have a port speed specified on the SIO command line in the 
CONFIG.SYS, the the port is "floating" as far as OS/2 and SIO are concerned.
  ie: DEVICE=D:\SIO\SIO.SYS (COM1,3F8,4,-)
                            (COM2:115200,2F8,3,-)                             
(COM3:115200,3E8,7:4,-)
                            (COM4,INTERNET:2E8,NONE:3,-)
                            (COM5,INTERNET:1F8,NONE:3,-)
                            (COM6,INTERNET:1E8,NONE:3,-)
                            (COM7,INTERNET:4F8,NONE:3,-)
                            (COM8,INTERNET:4E8,NONE:3,-)
COM1 is floating, COM2 and COM3 are locked at 115200 and the other five ports 
are virtual modems ;-)
