smpp 3.4 DLR's

Hi,

I've just started using the dlrmask 31 for an application to track when
messages get to our smpp provider, however the DLR code to say its been
submitted i thought was 8, however this is the log from the bearerbox access
log:

2003-08-01 17:43:33 send-SMS request added - sender:smpp1:+447766xxxxxx
195.224.50.164 target:+447789xxxxxx request: 'test'
2003-08-01 17:43:33 DLR SMS [SMSC:smpp1] [SVC:smpp1] [ACT:]
[from:+447766xxxxxx] [to:+447789xxxxxx] [flags:0:0:0:0:12]
[msg:11:0x00000000/] [udh:0:]
2003-08-01 17:43:33 Sent SMS [SMSC:smpp1] [SVC:smpp1] [ACT:bill 123]
[from:+447766xxxxxx] [to:+447789xxxxxx] [flags:0:1:0:0:31] [msg:4:test]
[udh:0:]

As you can see in the middle line, the flags show the dlr as 12 - is this
correct, or am I missing something?

Cheers - Bill.
