Apr 30 09:07:06 <brolin_empey> I know I should search the Internet by myself to try to answer my question but it occurs to me tonight after my bedtime that I may be able to buy a COTS adapter to split the microphone and speaker signals from a single 3.5-mm plug using the OMTP or CTIA wiring standards to two separate 3.5-mm plugs for use on my stationary and portable computers that have separate connectors for analog audio output and input instead of having only one connector for both 
Apr 30 09:07:06 <brolin_empey> input and output like on my mobile, specifically handheld, computers.  Does this typ of adapter exist as a COTS product?
Apr 30 09:12:49 <brolin_empey> I meant “type”;  I am not fluent in German (although I know a bit) so did not accidentally write the word in German instead of English.
Apr 30 09:23:33 <inz> Something like this: https://www.amazon.de/DuKabel-Splitter-Vergoldet-Geflochten-Kopfh%C3%B6rer-TRRS-Buchse-2-TRS-Stecker/dp/B07VK6F7L5
Apr 30 09:41:36 <brolin_empey> inz: Yes, thank you.  Apparently the customer service telephone number for this product is a +86 (PRC, specifically mainland China) number.
Apr 30 09:43:31 <brolin_empey> I mean because the SARs of the PRC have different telephone calling codes than mainland China if I recall correctly.  The “other China” AKA Taiwan is +886.
