How do I create a /dev/ttyACM0?

Andriy · 06-29-2006, 12:19 AM

I could not find /dev/ttyACM0 in my /dev. Only /dev/ttyACM1-3 are present but not 0. I was wondering how do I create one and the symlinks to it which will serve a similar purpose as those ttyACM1-3.

Thanks in advance guys.

Code:

mknod /dev/ttyACM0 c 166 0
ln -s /dev/ttyACM0 /dev/modem

Assuming you want to connect a modem and you've proper modules loaded..

hmm... i dont think i want to connect a modem, but if the mobile phone i want to connect uses the same protocol as how a modem does then i think you are correct. am i right?

btw, I get a "ln: `/dev/modem': File exists" whenever i tried to link it with /dev/modem and it seems that it's symlinked with ttyS1 rather than ttyACM0. should i delete /dev/modem and create a new symlink?

Which distro are you using? With recent distros, udev creates the appropriate device files for you.

Use ln -sf to force linking.

With all due respect, this is the slackware forum. I use 10.2 for your information sir.

However, according to this:

I think i should wait until /dev/ttyACM0 gets detected by any apps that uses the ppp protocol. so, linking it to /dev/modem directly would seem likely to be a last resort. I still haven't tried it, perhaps later when I have enough time. Thank's for your positive insight
