This is a short guide how to manually get GSM going.
Our default images all have a getty running on /dev/ttySAC0, please edit /etc/inittab and disable the getty on that port
NOTE: You don't need this in kernel builds with patchset ≥ 1288 |
To keep the kernel from writing to /dev/ttySAC0, you need to use dmesg -n1
.
