Initially, I need a program that will open two COM ports (real ones) on my PC. Send CONFIG script to modem attached to each COM PORT. Send data (text) patterns of various sizes from each COM PORT to the other (the data will travel from modem-to-modem). Monitor results of data to check for corruption, delays, etc. This should be very basic, but it is to be a building block that I can do some enhancements on, and the winning bidder may also be invited to do further enhancements on, over time, as the project evolves. I am not certain which software will work best - Visual Basic 6? Something relatively friendly as I must be able to go in and make small changes from time-to-time. More detail regarding the user interface, as well as future plans, can be prodived as necessary to interested bidders - ask specific questions for specific answers. Thank you.
