How do i connect 4 or 5 dumb terminals to a single system,those dumb terminals doesn't have any CPU?

Question

Those dumb terminals have only monitor,Keyboard,mouse with no CPU.

Answer 1

Dumb terminals have a CPU, just not much of a CPU.

But that aside.  5 terminals to a single computer. Have the single computer have a digiboard with 5 serial ports.  I have seen and used digiboards with as many as 16 ports.

Accessing and seperating the 5 or 4 serial ports would be done by giving each serial port a unique HEX code.  on windows /dos ,  win/tel class computers, they come with 4 serial addressable ports standard.

A lot of the unis servers do too. and it depends on the type of computer that you connect to.  What kind of expansion board you put in th ecomputer.

to specificall answer you question, "digi board".

Answer 2

you need to connect them to a server/system through a serial port.  You will need to add serial ports to the server...
