    I’m using a MTD-H5 on a BeagleBone Black running Debian. I’m able to connect to the internet no problem. When I try to send SMS messages however I get an error.

    My modem is on ttyACM0.

    I’ve installed and use sms-utils. The command I issue is:

    sms -d /dev/ttyACM0 send 1234567890
    [ERROR] atcmd.c:atcmd_write:389: full_write failed: Resource temporarily unavailable

    Any thoughts?

    If you tried to send the SMS while the ppp link was still active on /dev/ttyACM0 I would expect this type of error. The USB driver for the MTD-H5 creates 2 ports that you can use for applications (/dev/ttyACM0 and /dev/ttyACM3). If pppd is using one of these device nodes, try the other one for your SMS application.
