Selected Telephony Device already in use

I'm trying to connect to COM2 on my XP Professional
machine. The application I'm trying to use keeps coming
back with "Unable to open COM2".

I've tried a Hyperterminal session and get the
message "Selected Telephony Device already in use by
another application". I know I don't have any
applications running. Everything works fine when plugged
into COM1 - but I've already got something plugged into
COM1 normally.

I seem to remember having this problem before and it was
down to a missing file, or something that has been using
COM2 in the past not uninstalling cleanly. There is
nothing showing in Add/Remove Programs so I'm stuck.

Can anyone help ?
