Basically I have a list of devices that I need to connect to on a daily basis. Using an Access Server with 30 modems I want to manage and control the utilisation of the modems. So when I finish collecting data from a device I'll close down the session and then I want a 'session controller' to start another collection process to a different device. So I utilise the modems as much as possible at all times. The modems are accessed via a pool so I use a telnet and tcp port to initiate a modem connection. Hopefully that explains the background and what I'm trying to achieve better.
