Direct to COM port

Hi everybody.

I'll posting this to more forums as I don't really know where it belongs ...
Problem: Is there any way (or a component) that would allow me to send specific data to a selected COM port.
I do not know how exactly COM port works but I am looking for something that if told would send for example 123 to COM1 or COM2.
So is there a way how to acomplish that?

TIA.

Use the MSComm control in VB

The MSComm1.CommPort property lets you set the COM port you want to use.

Or simply

VB Code:

Open Com3 For Output As #1

But if you need more then just sending info. I think you should go with the MSComm Control

Well, don't know yet which method will be better but I need to comunicate with cash register and actually I don't know yet whether it is two way communication or one way. Well, I'll see. Thanx.
