Then I can't understand why it is not working.
This I made for Apple: https://dl2rum.de/rotor/Rotor.mov

Just to be sure, I checked again the serial com with rotctl:
rig_flush: called for serial device
serial.c(629):serial_flush entered
tcflush
serial.c(661):serial_flush return(0)
write_block called
write_block(): TX 7 bytes
0000 41 5a 20 45 4c 20 0a AZ EL .
read_string called, rxmax=32
read_string(): RX 15 characters
0000 41 5a 33 35 39 2e 38 20 45 4c 2d 30 2e 32 0a AZ359.8 EL-0.2.
easycomm_transaction read_string: AZ359.8 EL-0.2

What is rotctl?
In the query string is an additional space before the end terminator. Rotor doesn't send it, but this shouldn't matter when using the original Arduino sketch. Do you use the original SARCNET sketch?

rotctl is the rotator control as part of hamlib (rigctl and rotctl).
Yes, I'm using the original Sarcnet Arduino script version 6.
