when a PC needs to hit a SQL Server, port 1433 has to be opened. Does it have to be bi-directional or uni-directional is enough?

It should be unidirectional. Only the Port 1433 on the Remote Server should be opened up to be able to be accessed by the PC.

dba2dba- with Reads, the direction would be towards the PC and with writes, the direction is towards the SQL Server, right? still unidirectional is enough? is that a special property of port 1433?

Normally, If you want to connect to the SQL Server from PC. You need to have the port 1433 open for communication.

Once the Port is Open you can do reads from the SQL Server as well as writes to the SQL Server.

To see if you will be able to access the port, telnet from command prompt of PC to the specific port on SQL Server

In cmd prompt of PC:

telnet SQLServerName 1433

You should see a blank screen which indicates that you are able to access the port. 1433 does not have any special properties.
