USB-485 driver under linux modprobe

hello one and all,

 

i have a linux box and i have the AT-SERIAL.tar.gz file and its drivers *.c files under that tar file.  how do i use these to install the USB-485 hardware to get the kernel to list the hardware as a tty* or ttyUSB* device under /dev?

 

the USB-485 device does show properly under lsusb as like:

 

Bus 001 Device 004: ID 3923:703c National Instruments Corp. USB-485 RS485 Cable

 

and the kernel finds it also under dmesg | grep 1-1.2, which lists the links for the device under /bus/sys/usb/devices with the proper above idVendor=3923 and idProduct=703c as under the above ID.

 

but i can not figure out what to do with the AT-SERIAL files, which there are essentially 4 of them, FIFOtrigger, rs485, serialtest, and termisos_program, and install or get them into the modprobe or /sys/bus/usb-serial/drivers or /sys/bus/usb-serial/devices to translate the usb device into the tty* or ttyUSB* device.

 

does that make sense?  how do i do this?  thank you in advance, lucas

Hi slucas,

 

Have you taken a look at the  Using AT Serial with Linux manual? It provides specific instructions for setting up devices such as the 485 for Linux.
