Probably meant milliampere, specifically 1 milliampere. But yes, usually lightweight engineers are familiar with TTL and limit themselves to 5V. 12V+ is another arcane realm you don't want to touch.

Some old serial ports had 12V and a high max current. The DIY things you attached here were prone to kill your mainboard.

Voltage/current is either 0 or 1. Anything higher kills software developers instantly.

In telecoms 48V dc is very common and not always even connectorised! It's "safe-ish" but DC makes me more nervous than 240v, big thick 400A cables into a rack are quite intimidating to see but the main issue is DC is sticky and doesn't have the safety protections of RCDs etc. Indeed you are lucky to get a working isolator.
