I setup com0com on my Win 10 machine and created a pair of ports com3 and com6. I ran two copies of hyper terminal, one on com3 and one on com6 with local echo turned off. I expected com3 to send input to com6 and vice versa but that didn't happen. Com3 appears to have RX and TX tied together since I see the characters I type. Com6 doesn't do anything when I type, no local echo and nothing on com3. Can anyone suggest what is wrong? Regards, Bob
