Hi all,

I have a telescope server, built for G4 OS X 10.43, that needs to be given a dev that is connected to the telescope. The scope is RS232 serial, the Mac is USB. I got a USB to RS232 serial adapter which Tiger recognizes as such. But I need to have a device such as /dev/ttyS0 that I can give to the telescope server so it can connect to the scope.

Is there anyway to assign one to a USB port? Is there such a thing as /dev/USBx?

It has been a while, but I seem to recall USB to serial bridges being /dev/tty*. The easiest way to find out what the * is will be to unplug the dongle. From the terminal type 'ls /dev/tty*'. Plug in the dongle. From the terminal type 'ls /dev/tty*'. See what new /dev/tty devices you have. Wait a minute or so after unplugging or plugging in the dongle before typing in the command so that driver has time to detect the changes.
