    Does the reader work? If not, are there any lights on the reader? Have you check the wiring to the reader? Have you swapped out the reader?

      Check everything

      I ask this , was the unit working or has this been reciently installed ? COM errors sugest to me your either running a flavor of linux or if a MS product you have a faulty wire between the unit and the server . With server 2k series the ports are automaticly configured , with linux its a do it your self process . there could be a problem with drivers as this is not a standard computer peripheral . This is all academic with out being able to look at the unit . Another sugestion is to check the fuses (inline and internal ), the wiring to the readers , the software settings and even the power cord (believe it or not it has happened). check you IRQ's they have been known to cause errors . When in doubt spend the money to get it looked at by a professional . I don't want you to get too specific as we are talking about your security but this is like going on a doctor's forum and asking , I have a hole in my chest how do I stop the bleeding ? it depends on how the hole was created weather or not its a stab wound or a bullet wound . two different fixes for the same problem . I don't want to sugest replacing know good parts for parts of unknown quality in this price range but test everything in your power.
