[nos-bbs] Comm port

Jerry:

I have never used JNOS under a windows platform, so I am not sure how to help you. (I use Linux)

One thing you can do, is if you have more than one USB port on your computer. Every time you unplug the adapter, and plug it into a different USB slot, you will get a different COM port number. If you plug it back into a port that it was once already in, you will just revert back to the COM port number that was origianlly assigned to that port.

By moving to another USB slot, you might get an unshared COM port.

Now, as mentioned by others earlier, in JNOS, I'm used to configuring a port using the TTYS# statement. (Where '#' is the COM port number)

So, in your case, you state that you get COM4.  Then your JNOS parameters might look like this:
--------------------------------------------------------
# COM PORT 4 (external KPC3+)
#================================================
attach asy ttys4 - ax25 ax0 4096 256 9600
#
ifconfig ax0 ipaddress 44.2.14.1
ifconfig ax0 description "145.050 MHz"
ifconfig ax0 ax25 bctext "GVCITY Node - Grass Valley, Ca."
ifconfig ax0 ax25 paclen 128
pause 1
#
--------------------------------------------------------

I hope this helps in some way

Bill,

Thanks for the quick response. This is a Windows XP computer. I got the comm port number that is 4. What I need for the attach statement is the IO address and the vector or interrupt. I found that information from the control panel and computer administration but I find a shared interrupt 16 and a very long IO address compared to for standard com1 having an unshared interrupt 4 and 0x3f8 address. I'm told a shared interrupt will not work with JNOS and I can't force the address to the common com1 data.

This is a Windows XP computer. I have used the USB to comm adapter on a terminal to tnc connection successfully using the Winpack software but we can't find a way to attach in JNOS. Have you or anyone else ever used a USB to comm adapter for JNOS?

Jerry, N0MR

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.
