writing the variable value on port.

[jjbabu]

hi to all,
regarding my project,i used qextserialport to communicate my gui with serialport.upto now i did evrything fine,but now i got one problem,i have to write the varible value on the port,while am using port->write("i");// 'i' is variable function instead of giving 'i' value simply am getting 'i'(charactor) on my hyperterminal.how can i avoid this.
please provide some help with sample code or atleast function prototype.
thanx in advance.

You certainly shouldn't surround the variable name with quotes... And depending on the type of "i", you might need to convert it to a string.

You are writing "i" string to the port, not the variable. If you want to write variable's value, you have to first convert it to a byte array.

You need something like:
port->write( QString::number( i ).toAscii() );
