ASCII to PDU convertion and back

[DraguVaso]

Hi,

For my SMS-application I need to be able to send characters with accents
(like é and à). But this doesn't seem to work in Text Mode, so i will need
to do it in PDU Mode.

Does anybody has soem converting routines for that in VB.NET? I need my text
to be converted to a PDU-message, and back (for received messages).

Thansk in advance,

Pieter

How did you try to do it in text mode? You'll need to know the encoding
to use, of course. Note that characters with accents in *aren't* part
of ASCII.

http://www.dreamfabric.com/sms/ seems to have quite a bit of
information in it...

I tryed to set them just in ir, but that didn't work.
for exemple:
AT+GMGS="0486112233"
This is my message with accents éà<Ctrl-Z>

Do you know the way to send the accents in text-mode? I assume it must
exist, but I can't find how :-(

Pieter,

I do not know this stuff however afaik is Frites written as you see here,
not Fàités.

I was curious so I have looked at some pages and I found unicode 8859-1

http://www.dreamfabric.com/sms/

What is the standard in our language zone as far as I know.

http://de.wikipedia.org/wiki/Windows-1252#Windows-1252

(And I am curious where do you use that à and what kind of keyboards do you
use Querty or Azerty?)

I'm not using an API: I'm using VB.NET 2005 with the SerialPort-object, if
that is what you mean...

Well, that *is* using an API. Anyway...

Anyway, how are you then writing the data to the port? Are you writing
a byte array, or a string? Either way, what encoding are you using?

I'm really having troubles to udnerstand what you exactly need to know...

I'm writing a string all the time.
Some of my routines:

Public Sub PinInsert(ByVal strPin As String)
ModemStatus = enumModemStatus.PinValidation
WriteToComPort("AT+CPIN=" & strPin & cstCR)
MessageSilent("Inserting the Pin...")
End Sub

Public Sub SetToTextMode()
ModemStatus = enumModemStatus.TextModeValidation
WriteToComPort("AT+CMGF=1" & cstCR)
MessageSilent("Setting to TextMode...")
End Sub

Public Sub WriteToComPort(ByVal strMessage As String)
SerialPort1.Write(strMessage)
End Sub

Public Sub SmsSendNumber(ByVal strNumber As String)
ModemStatus = enumModemStatus.SmsNumberSending
WriteToComPort("AT+CMGS=" & Chr(34) & strNumber & Chr(34) & cstCR)
End Sub

Public Sub SmsSendMessage(ByVal strMessage As String)
ModemStatus = enumModemStatus.SmsMessageSending
WriteToComPort(strMessage & Chr(26))
End Sub
It works really fine with just normal text, but once I begin using accents
the accents don't come through....
strMessage is like this: "hello world" or "érica"

Okay, that's the bit I needed to know - you're using whatever encoding
the SerialPort class is providing by default.

Try changing that to ISO-8859-1:

SerialPort1.Encoding = Encoding.GetEncoding (28591);

Thanks, I changed it and tryed to send some messages but I always got this
answer when I got accents in it:

"met accenten hé jà bèkes

And not the "+CMGS: " that I normally should receive...

Even messages without accent don't work: there I get this as an answer for

Do you understand those messages? I don't know the language, I'm

Messages without accents shouldn't be affected at all. Print out which

I added three things here:

- The encoding before I change the encoding
- the encoding after the changes
- how I open the port and change the encoding

The "met accenten hé jà bèkes" and the "zonder accenten" are the SMS that I
tryed to send: they are dutch...

Ah, I see. Well, sending "zonder accenten" should be identical whether
you're using ASCII or ISO-8859-1.

On the other hand, I see you're using an unprintable character at the
end of the text. I'd strongly recommend sending any binary values as
bytes rather than still using the encoding for that.

Given that you're setting it to "text" mode though, I wonder whether
you might not be limited to ASCII anyway - you may need to change
something else to use non-ASCII characters.

err... so trying to change to PDU would be the thing to do... :-/
Althoug I'm looking almost a whole day on that stuff, and I still wasn't
able to send a message with pdu :-(
