n6110 FBUS: delete sms after receive

[Piotr C.]

Hello,

After the initialisation of n6110 (230 x 0x55) and sending any request,
phone reports its state by sending apropriate frame w/out a request. Eg.
when sms is received, i got:

00:  1E 0C 00 02 00 4C 01 08 00 10 02 01 00 07 91 84
10:  06 92 15 11 F1 00 0A 01 87 04 00 00 24 07 91 84
20:  06 02 F0 00 00 00 00 00 00 20 11 61 91 81 80 40
30:  C8 22 93 F9 54 BC 8A F2 B0 0E FA BE A7 E9 61 77
40:  3A AC 6B A5 8E EC F7 FC 7D 2F 83 54 B7 18 0C 06
50:  01 42 C5 DA

I wrote a simple program which decodes it. It is:
  SIM position (?) : 1
  SMS center: 48602951111
  sender: 4860200 (internet gate)
  message: HELLO (...)

Now I'd like to detele this sms automatically. I send frame like this:

1E 00 0C 14 00 08 00 01 00 0A 02 01 01 4x xor1 xor2

and receive no ack frame from the phone. It doesn't matter the pos.# and
seq.#; no action is taken. What am I doing wrong? How to delete sms so?

Regards
