[mythtv-users] Issues with serial port

[Gabe Rubin]

Hi list,

I am trying to change channels on my DCT-2200 series box using the
channel changer script in contrib.  Problem is, I don't my computer
recognizes my serial port.  The motherboard I purchased does not have
one so I purchased a PCI add on card that has two USB ports and a
serial port.  How do I get my computer to recognize the serial port?

Evidence that it is not recognizing it:
 channel -v 5
channel: /dev/ttyS0: Input/output error

And this:
[root at localhost ~]# dmesg |grep Serial
