OK,
Im running Mac OSX 10.6.4

So i have a Prolific 2303 Serial to USB port.
Im trying to use this with Z-Term to connect to Cisco Router.

I originally followed this guide:
Add a serial port to your Mac

my :
Product ID: 0x2303
Vendor ID: 0x067b
(as it read in my System Profiler)

Originally this was working. I could connect using Z-Term and all was well.
The very next time i started up the program and tried to connect, it could not find the usbserial device.

I have looked in my /dev/ folder and there is no entry for tty.usbserial
i used this command in Terminal :

ls -la /dev/tty.*

Not sure if thats the issue ? But seems to be missing a tty file?
Basicly in Z-Term when i go to Settings > Modem Preferences , there is no serial via usb option anymore (there was the first time i set it up)

Other thing i was thinking, maybe Z-Term locked the tty like Minicom can do on Linux?

Any help would be great, busting a blood vesstle on this one....

Cheers

Is there an answer to this post? I'm having the exact same issue. The tty.usbserial file is missing from /dev directory. I only see two blue tooth files listed and nothing for the usb to serial dongle I have on my macbook pro. Everything was working until I upgraded to Lion and it quit working. Now the file does not exist. Any help would be great.
QUOTE Thanks
