SERIN Formatting

KevSwannUK

Hi All,

Can anyone help sed some light on this little data formatting problem I have. Basically I'm reciving some serial data from a GSM modem and I want to capture a specific part of the serial string.

Here is the string I am receiving...

+CMGR: “REC UNREAD”,”0146290800”,”98/10/01,18 :22 :11+00”,<CR><LF>ABCdefGHI OK

The section I need to get is the phone number 0146290800 only without the " symbol.. the best I can come up with is:

I know I want do do something like:

PNumber VAR Word
Serin RxD, B4800, [noparse][[/noparse]wait("+CMGR:"), wait(",") , SKIP 1, PNumber\???]

I'm not certain what I need to put after the PNumber. As the number always ends with a " how do I set this to be the end marker? It seems simple with any other character "*" for eample, but is """ valid?

Thanks in advance

Kevin

PNumber\???

if you know that the phone number is always 10 digits long, you can just put

PNumber\10

Basic stamp will stop recording digits/characters at 10 bytes.

Thanks Boris... If only life was so simple...

Unfortunatly the number can be any lenght from 8 to 16 numbers... Any other ideas?

Have a look at the STR modifier of SERIN with the \Length and \End-Character parameters.

Jon, Thanks

Yes that is what I have looked at, but is ... PNumber\"""] valid? i.e. can·" be used as an end character?

Thanks

Try this little demo -- baud is set for use with the DEBUG terminal and a BS2:

Quote           CON     34


buffer          VAR     Byte(10)


Main:
  DEBUG CLS, "Enter test string: "
  SERIN 16, $4054,
        [noparse][[/noparse]WAIT("+CMGR:"), WAIT(",") , SKIP 1, STR buffer\10\Quote]
  DEBUG CLS, STR buffer
  END

It worked for me using your test input.
