COM Port Not Working on Windows Terminal Server

Microsoft says, “TAPI is not terminal services aware.” Apparently, this applies to using HyperTerminal to connect a serial port to a SAN, router or any other device through an RDP session. It will redirect the local COM ports to the server without any issues though. I lost thirty minutes of quality time to this issue today. Uninstalling Terminal Services resolved the issue. Thank goodness it was just a lab server. Maybe this post will help some other hard-working IT professional get home on time. See TAPI is Not Terminal Services Aware for details.
