I am using sms tools 2

and tried it on sony ericsson z530 and sony erricson w810i

on windows vista ... tried with bluetooth connection and cable connection ... all failed!
(also tell me how to get my correct com port number ... I took the one that is installed like serial link com port driver with bluetooth or cable drive installation.)
PLEASE HELP!!

First check from the Sony Ericsson manual what is a supported baud rate and if you cannot find this information, try using baudrate = 9600 or baudrate = 19200.

Phone driver or bluetooth driver should say what COM port is used. If you cannot find installed port from device manager, you just have to guess and try it.

First serial port in Cygwin is /dev/com1. From the device manager you should at least see what fixed COM ports are available, like COM1 and COM2. For example start with /dev/com3 and try the next and the next until the lost port is found. Notice the naming, use slash instead of backslash.
