I have a project of interfacing and programming an Intel 8031 and a 16550 based UART. Currently, I can transmit to another port ( on a separate computer) with no problem. My down fall is on the receiving end of the task. I get framing and overrun errors even when I use the internal loop back test. I'm not normally this stumped. Has anyone else completed this task? Does anyone know of a 8031/8051 group with a large knowledge like this where guys aren't asking how a resistor works like the basic stamp site? I'm not trying to flame those who are out there and trying to gain basic knowledge, I welcome it! I do, from time to time however, need a more advanced group of individuals that have been down a road I have not taken. Thanks in advance for your help Sincerely, Cory M. Kutchera
