I did a little investigation. What I saw in the log I sent you
is that apparently the phone sends some unexpected packet of
data. In order to test this I added an extra call to SM_Block
in function GetSMSCenter, file nk6100.c:

static gn_error GetSMSCenter(GSM_Data *data, GSM_Statemachine *state)
{
 unsigned char req[] = {FBUS_FRAME_HEADER, 0x33, 0x64, 0x00};

 req[5] = data->MessageCenter->No;

 if (SM_SendMessage(state, 6, 0x02, req) != GN_ERR_NONE) return 
GN_ERR_NOTREADY;
 SM_Block(state, data, 0x02);
 return SM_Block(state, data, 0x02);
}

The extra call to SM_Block is supposed to absorb the unexpected packet.
It seems to work in principle, stdout reports:
No. 1: "Set 1" (default name)
SMS center number is +31626000230
Default recipient number is 221
Messages sent as Text
Message validity is 24 hours

Interestingly, in the log from the windows software each of the
transfers involved in getting the smsc has two extra bytes with
something that looks like a sequence number (0x142->0x144->0x146)
