German Translation, Serial Port?

Hello friends. I need a translation from a German manual describing serial port parameters. I used google translate but it doesn't quite give me the warm and fuzzy. Anyone here speak German? Here is what it says: Betriebsart: Asynchron 16 Zeichenl?nge: 7 bit (mit Sperrschritt) Parity: gerade L?nge Sperrschritt: 1 bit Google says: Operating mode: Asynchronous 16 Character length: 7 bit (with blocking step) Parity: straight Length of blocking step: 1 bit First, anyone have any idea what Asynchronous 16 means? (async I get, but "16"?) 7 bit with blocking step. Could this mean 7 bit with stop bit? Parity: straight. Could this mean odd or even? Length of blocking step. Could this be number of stop bits? I am attempting to translate some pages in this manual and would like to get this right (for others who may find this info useful). Thank you!!! (or should I say Danke?!) 73 Eugene W2HX PS. This is for an HF antenna coupler that can be controlled over a serial port.
