I also ended up modifying the permissions on the lock directory, but there's probably a better way to do that. That's why I compiled it with /var/spool/lock instead. If you trust the app, click Open to run it.

You’ll be warned that the app is from an unidentified developerin other words, it isn’t signed with a valid developer signature. This works on macOS Sierra as well as previous versions of macOS. There is no /usr/spool/uucp, or /var/lock, as mentioned in the man page. To open an unsigned app, you need to right-click or Control-click the app and select Open. (of course, that's because my application is to talk to a device at 9600N81, YMMV.)ģ) Notice the lock dir mentioned above. Serial Port Monitor handles RS485/422 as well as RS232, and supports Modbus RTU and Modbus ASCII protocols. configure -enable-dfl-port=/dev/tty.serial -enable-lock-dir=/var/spool/lock -enable-dfl-baud=9600 The Serial Port Monitor by Eltima Software has the ability to sniff communication from another program (without requiring a special cable) and the ability to monitor multiple serial ports at the same time. The developer doesn't seem in any hurry to rectify the situation. It hasn't been updated in five years or so, and isn't a Universal Binary. Two problems then present themselves: ZTerm is a horrible Mac OS X app. Here are some of the defaults I compiled into the program: I often have to do router configuration via a console port, so I use a Keyspan Serial Adapter to get access. Once this is done, it's easiest to just reboot the machine.Ģ) As mentioned above, the serial port is /dev/tty.serial. You might *think* of editing /etc/ttys, but you actually want to edit /System/Library/StartupItems/SerialTerminalSupport/SerialTerminalSupport - and edit the line halfway through to say,

Disable this before trying to use the serial port for other purposes. Here are a few things to be aware of re: the serial port.ġ) Just like any cisco router or HP switch, etc, the XServe is configured to listen with a secure terminal on the serial port, for config purposes.
