I am trying to connect a simple periferal device to my compaq nx9010 laptop (XP professional). The periferal uses the RS232 standard and comes with a cable and the option of using a 25 pin (only 6 are used) or 9 pin plug (I think the 9 pin plug is a DB9P). I have a socket in the back of my laptop with 25 holes arranged in to rows (very standard).
The device has software which I have installed on my laptop and my desktop machine as well for the purpose of testing only.
On my desk top machine (Win98) the periferal works fine.
The software that comes with the periferal allows me to select the COM port to use; on my desktop I select COM1 and it works fine.
On the desktop, in device manager under Ports (COM & LPT), I have listed COM1, COM2 and LPT1, fine.
However on the laptop in device manager I only have a printer port LPT1, no COM ports.
I figure that I need to set up a COM port on my laptop to get the periferal working.
How do I make a COM1?
