welcome to myadsl.
how do you connect to the device? On my phone, windows reports the connection speed as 115200, which is the speed at which I connect to my phone, not the speed at which the phone connects to the internet.
you have to use AT Commands to set up the connection to use HSCSD. you can download the
AT Commands for the P800/P900.
i cannot remember how to set a device to use HSCSD, but if i remeber correctly, you just set the CSD speed parameter to a higher speed.
to execute AT commands before dialing up, open up "Phone and Modems" in Control Panel, go the the Properties of your modem (phone), go to the Advanced tab and add the AT command in the "Extra Initialisation Commands" box.
EDIT:
it appears you have to add the appropriate AT+CBST and AT+CHSN commands in the modem initialization string to set the HSCSD speed.
To connect at the fastest speed use:
AT+CBST=81,0,1
AT+CHSN=6,0,0,0
You have to seperate the command with <cr> to tell windows that it i two commands:
AT+CBST=81,0,1<cr>AT+CHSN=6,0,0,0<cr>
The above will use the V110 (ISDN) protocol, which allows you to connect withing a second or two. If you phone does not support it, use the analog protocol:
AT+CBST=0,0,1<cr>AT+CHSN=6,0,0,0<cr>
