So my prime hobby is ham radio, and my prime mode is morse code. These days, we mostly connect computers to the radio to do logging and morse code keying (done through the LPT port). One popular program runs under windows. The big boys use another program that runs under DOS, and lately FreeDOS as a replacement. Running under windows, there is an annoying hesitation once every word or so that is due to whatever is going on in windows.

The solution, provided by the maker of the above-mentioned windows software is an external keying module. With this arrangement, windows sends characters to the hardware brick, which, latency-free, sends out the characters quite nicely. (Amazing how the trained morse-code ear can distinguish ms delays in character starts.)

Personally, I now think that way where a system has a component that is latency rich connected to a component that is latency-free. This of course has implications to the overall solution.
