I am writing a program that captures another computers print output and using the data. Well here is the problem. When I have to prompt for action code stops so I lose data coming into the port(I am using a parrallel to serial converter). So I either have to write my own msgboxes(I already did the dialogs modaless) or disable my cts , but then the host computer will eventually timeout and have to reprint. I did test an activeX server just to handle and stack input but It was alot of extra code And I'm not that educated on it. I know there is a way to do it. Does anyone have any Ideas how I should fix my problem. I am just not sure what is the best road to take. This progam will be used allot and must be solid(like any good prog). Any insight would be greatly appreciated. thank you
