Hi Guys,
Im am just inquiring if anyone knows if PDU mode works on this modem using AT commands? It works using the normal text mode but everytime I try in PDU mode I get a 304 error. I am testing through a putty telnet session and have used the converters on the following websites to help with the PDU conversion but nothing works for some reason.

I have also ensured that the router is in passthru and PDU mode using the AT+CMGF? command
Does anyone have any experience / ideas on this.
thanks Callum
