So this question might be better geared for a users forum or list but I'll give it a go here first since you guys have been so helpful. The instructions for the g_serial driver indicate that you should use minicom from the host side. I'm already using minicom from the host side in order to communicate with my board. I also don't have minicom on my gadget board. Is there a way to use the device without minicom or from the command line? I'm guessing that in both the host and gadget case I'll need to open each device in an application and use write() and read()? I'm guessing that minicom opens up said devices and performs reads and writes to the generic serial device drivers? Can someone point me in the right direction? Right now I mostly just want to verify that things are working, so if I can do a echo "Hello world" > /dev /ttySG0 or something else. Thanks for all the help.
