[nos-bbs] Comm port

[Wm Lewis]

Jerry:
 
I have used many of these before.
 
This issue is only medium in technical aspect.
 
First, think of older computers that had the 9 pin serial ports. Each of these gets assigned a COM port number.
 
If your computer had two of these ports, windows would assign one "COM1" and the other "COM2"
 
When you plug in a USB adapter that has a 9 pin serial plug, you need to do the following:
 
1 - Make sure you install any software that came with the adapter.
2 - After the software is installed, plug in the USB adapter.
 
At this point windows will assign a "COM" port number to the device.
 
The NUMBER ONE ISSUE most users have at this point is figuring out what that COM port NUMBER is.
 
>From here you need to open the WINDOWS CONTROL PANEL.
 
Next double-click and open the "SYSTEM" link.
 
When the "System Properties" tab opens, click "HARDWARE", then click "DEVICE MANAGER".
 
When the "Device Manger" loads, scroll down and expand the "Ports (COM & LPT)" menu.
 
Now, my adapter is a Radio Shack USB-to-Serial Adapter. 
So, on my computer, when I expand that menu, I seen one line that reads this:
 
"RadioShack USB-to-Serial Comm. Port (COM2)"
 
So, from this, I now know that the COM port that got assigned to my adapter is COM2
 
You wont always get a "COM1" or a "COM2". Depending on your computer assignments, you could get a "COM5".
 
Now there are some follow up rules to know and understand.
 
#1 - If you unplug your adapter cable, and plug it into A DIFFERENT USB SLOT, you will likely get a new "COM" number assigned to it.
#2 - Some older "packet" softwares (usually DOS) have no ability to select a COM port higher than "COM2"
 
Hopefully this helps you to figure out what COM# you need to use when assigning ports in JNOS.
