[nos-bbs] Comm port

[N0MR]

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.
