I have been using the HHD product for several years now - it is a really useful program and works rather well. One thing - the program can do the Protocol Monitor job, using two serial ports on a monitor computer. You connect the PA computer between the devices which are talking to each other and it will display and record both sides of the conversation. A very useful capability when you have to reverse-engineer a communication protocol which isn't communicating. The company has several other useful utilities - I tried several of them, but so far have only purchased the Serial Monitor. Roy J.
