It’s been around since OS 8 (for those of you who can remember back that far!).
We’ve also been using ZTerm – which is a stalwart of the USB to Serial empire on MacOS. Recently, a number of network devices have started shipping with in-built USB ports that we need special breakout cables to support, and have had great difficulty getting OSX to support them properly. There are a number of companies that make them, and we can pick them up for about $10. Programs that support talking to a Serial Port are even harder to find.įor a long time, we’ve been using the Prolific PL2303 adapters. The drivers for the USB to Serial adapters are hard to find, rarely work across OSX Version upgrades, require special processes to “authorise the driver” and are often buggy. USB Serial support in OSX has been a pain in my backside for years.
