Hi!
I'm trying to do a GSM-link to one of my temploggers, I bought two
Siemens
M20T units.
I have no problem connecting them to exchange characters in the
terminal
software.
But exchange data doesn't work at all.
By connecting a 'sniffer' to the serial input of the logger I can
see that
it gets the same characters as if I used a serial cable, but it
desn't
respond.
The logger works on 9600bps, unfortunately I don't know if its 8N1,
but i
think it is.
Anyone with better knowledge in this than me, who can give me a hint?
Any internet resources I should read?
regards!

but my data is in a logger ;(
What settings do you have for the communications?
Xon/Xoff?
Do I need flow control in hardware?
Which baudrates are recommended? is 9600 too high?
Regards!
