I have a WonderWare application at my main site that I need to have communicate with a SLC-5/04 at a remote site via a modem. I am using the ABKF2 I/O server. I dial up the modem and use the escape code (+++) to release control of the modem and then start the ABKF2 server. The ABKF2 server won't take over the modem because it says the modem isn't free. Does anyone have any other suggestions?
