This tool has been extremely useful for me. There is one problem I haven't gotten around yet. I'm regularily checking to see if other PCs have "logged on" so I'm doing a jtcp('accept') command triggered off a timer. The problem is that if the PC is not logging on, then I get a timeout as expected, but it hangs the port. I added a try/catch, but this kicks the jtcp routine back before it closes the port so I have the same problem. I'm sure it's my lack of how to use the tool properly, but if you have any suggestions, I would appreciate them.
