Text vs PDU mode & the SMSC

[Richard Herselman]

Dear List,

I'm using gnokii 0.6.26.dfsg-3 from the stable repos on a Debian Lenny 
5.0.3 box with a USB flip-flop device. I can query the modem at 
/dev/ttyUSB1 with gnokii --identify etc.

1. Is there any way to force gnokii to send SMSs using text mode and not 
PDU mode? The device seems to supports both, but our network operator 
only supports text mode, so trying PDU mode won't ever work.

2. Is there any way to permanently set the SMSC number, e.g. in the 
gnokii config file, or otherwise customize the AT commands that gnokii 
sends (short of trying to hack the source code)? I've been unable to 
have gnokii retrieve the SMSC from the SIM card, even though the "SIM 
message centre" setting shows the correct number when I install the same 
SIM card in my Nokia phone.

Running "gnokii --getsmsc" gets me:

[...snip...]
Received message type 23
No. 1: "" (default name)
SMS center number is
No default recipient number is defined
Messages sent as Text
Message validity is Unknown
Error: The given memory location is invalid.

With regards to my first question, here is the output from running 
"gnokii --sendsms 0821234567 --smsc +27829119", where it shows "PDU mode 
set", no matter what I try:
