How can the 9 pin serial port be used for synchronous commuinicaiton.

Assuming you mean on a PC?, I don't think it can, it's an asynchronous port only.

What do you have that requires a synchronous connection?, it's pretty unusual.

indeed, it cannot be used for that. you need the 25 pin serial port (male, not the female printer port) wich has dissapeared from pc's for several years now.
 
Iam in way of developing a PC based tuned radio, where most of the tuning IC's require 3 wire sync serial commu.
so which port can be used for sync serial communications. from a PC.

The parallel port can, which is how most PIC programmers work, or you can use the handshake lines on the serial port - but it's rather more difficult because of the voltage levels involved (+/-12V instead of 0/5V).

A better option is probably to have a PIC in the radio, allowing it to work on it's own, and include a serial interface for control from the PC via the PIC.
