StartReceive error on demo?

Hi, I'm a happy paying customer of the source for alt.sms.smppclient, but we've been having issues sending messages on one of the SMSCs that we connect to. (just recently got the latest source from you, so it's the latest version)

Even when i run the latest demo, i still crash the client, here is the output:

SmppClient connected

any ideas?

thanks!

It looks like you connect to SMSC which use SMPP version greater than 3.4.
Your SMSC sends submit_sm_resp with TLV options. I'll try to extend my parser to avoid such errors.

Hi (Alex, is it?),

thanks so much! I would really appreciate that!
Is there anything I can do in the meantime to "swallow" these TLV options so they don't crash the application?

Thanks again,

Sam

also, so i can tell the SMSC, how did you know that the SMPP version they are using is higher than 3.4?

Thanks!

Sam

because in the specification 3.4 SubmitSmResp has no TLVs.
