however, the scantool program works just fine, no problems. i have the plugin set up exactly like the scantool program is set up, com4 baud 9600.
i even tried launching the scantool program from CF... works fine. no dice for the plugin though

my elmscan firmware is revision 2.0 if that helps... car is '06 subaru impreza
any ideas?
make sure you do not have navigation set to COM4... You can also enable logging in OBDII and post the log for more information...
