Jerry you may want to try a simple terminal program such as the one that came with Outpost - ipserial, I use the one from the SantaClara ECS group. or the one that came with RMS EXPRESS, for winlink. they work on my W7, Pro, 64bit. this is all manual setup, and crude compared to the UISS software modem, but it works. good luck 73 Christy KB6LTY
