serial object doesnt like FTDI usb to serial adaptor on OS10.9

May 31, 2014 | 11:22 pm

im trying to use an FTDI based peripheral with the Max serial object and im running into this issue: max only seems to find the /dev/cu.usbserial-XXXX device and doesnt allow me to use the /dev/tty.usbserial-XXXX device. furthermore, when i tell the serial object to use it, the max window tells me

serial: error setting tty attribute (/dev/cu.usbserial-A900M27O)

if i tell max explicity to use /dev/tty.usbserial-A900M27O as the serial port (instead of the a-z shortcut) I get the error

serial: specified port not available

in the Max window. Am i doing something wrong or am I going to have to write my own external for this to work? :) not that im opposed to that…

Apple add its own FTDI chips driver in Mavericks. But it needs to be disabled and FTDI’s original one needs to be installed…

Some infos here.
Hope it helps!

If you do your own external, I’d be interested to test it :)

hi ,
i ‘m also having troubles with serial interfaces that nevertheless appear in "system infos" , at the USB tab .
in Max , i can only get "Bluetooth-incoming-port" and "Bluetooth-Modem" .
i would say it seems to be a sort of "max problem" , but i’d like to test it on another software .
i don’t know yet which software i could try , to see if it links to the serial interface …
if you make an external , JRSA , i would surely say i’d be interested to ! …

hi ,
i had made a mistake , that consisted in not installing the needed driver , for prolific usb to serial adapters ,
now i have downloaded it (http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=229&pcid=41) ,
and i can access the serial output, from "serial" object .

sorry Cycling , hope you haven’t been spending a second on this …
