Does anyone know the correct AT command to drive the phone into HSCD ie 28BPS V34 or even V120 not sure if that is supported.

Well, this must be done before starting the call.

Type AT+CBST=16,0,1 and <cr> for 28800 bps V34, or
Type AT+CBST=79,0,1 and <cr> for 38400 bps V110.

Of course, you must type AT&W and <cr> after the above, to write these settings to memory, and then you can start the call (ATDTxxx....).

P.S. AT+CBST=0,0,1 is the default (autobaud) setting

Thanks for that. I wish to add them in the Modem addittional commands entry do I need the <cr> or will windows assume that ? Or do I need to use an ASCII CR

No, you don't have to enter <cr>. Let Windows manage with it! 😉
If you have any further questions, I'm here!

Good luck!

Thanks
