Serial port input device

Hey David,

Sorry for emailing you directly! I thought I posted here orginally :)

I have this exact same problem right now..

We are in the process of switching our class computers from superlab
to Eprime2. We used good Ol' cheap serial mice to record RTs in
superlab with no problems. I was under the impression that with the
new Eprime2 I can simply add a serial device which was the case when I
added the PST response box to our lab computer. However, when I tried
to add a serial device (aka serial mouse) for class projects and got
the same results as Daniel. Is inline script the only way to fix
this?  Really hope not...
