alt Hacker NewsThat really sucks for hotplugging since TRS connectors sliding in basically make random connections before seating properly.
Granted, you shouldn't hotplug TTL serial, but everyone™ does it anyway. (In some situations you're even forced to, to avoid reverse powering something.)
They're not random connections; they're predictable. I'm not worried about Tx briefly touching Rx or ground in these devices.
