I'm still trying to connect the FocusLynx to INDI.
Reading the thread "Serial timeout with Moonlite Focuser" Thread gave me hopes as in this thread a solution was published to successfully connect a FTDI USB/Serial focuser. Its not the same focuser as the FocusLynx but I tired to do the same as published there (installing the older version of the FTDI driver).
Unfortunately no success, still the "TTY timeout" message.
I can confirm that the driver is successfully loaded in macOS, the system report of the extensions confirmed this. The USB/Serial port is visible and available and INDI can also see the port, but cannot establish a connection.
Maybe this helps a bit in isolating the problem.
Greetings,
Thomas
