Hi!
Motorola Droid 4 runs packet protocol over serial... and its kernel
driver requires explicit "write()" boundaries at places where packet
boundaries should be.
So I can send SMS using low level g_at... functions (that are not
normally accessible), but not using g_at_chat_send().
If anyone has good idea for clean (or clean enough) solution, let me
know.
Best regards,

snprintf(buf, sizeof(buf), "AT+GCMGS=\r");
encode_hex_own_buf(pdu, pdu_len, 0, buf_pdu);
So speaking from memory, but 27.005 expects CMGS to be a two part
command. First you send AT+CMGS=<whatever> and the modem then prompts
for the PDU using '>'. Then we provide the PDU followed by Ctrl-Z. If
the Motorola modem doesn't do this, then you're stuck providing a full
Motorola-Hacked-AT-Commands implementation of your own.
You can try hacking GAtChat to add a bunch of behavior-modifications
like this, but I imagine that this protocol is different enough where
such changes become a nightmare to keep track of.
