absolutely... before my OS/2 system went TITSUP (Total Inability To Support 
Usual Processing), my first 8 nodes were all connected to POTS... all my 
virtual modems were attached to my nodes higher than 11 which left me nodes 9 
and 10 for local operations...

i went the above configuration because it was easier for me to have one 
catchall configuration for my POTS lines and separate ones for my virtual 
ones... that way i only needed to edit one file for any changes in my POTS 
setup and all those nodes would react as desired... my virtual modem nodes each 
have their own configs... make sure you set your TASK number as needed and 
inside fdconfig there's a section where you can specify the TASK/node number 
you are configuring...

what i did was to configure one node (eg: node 11) and then copy its files over 
to the other names and then change just the one or two things in them that were 
different...

  eg:
      copy MDCFG11.FD MDCFG12.FD
      copy MODEM11.FD MODEM12.FD

i also had separate EVENT*.FD files and others... if you don't have them 
numbered in your directory, they are used for nodes that do not have a specific 
one... which ever one the com port is defined in will certainly be different...

other files i had were specific to a node so i used my TASK variable in my file 
configs...

  eg:
      Log File:  $[FD]\FDN$[TASK].log

which would create the FDN1.log file where the FD= environment variable pointed 
to and use the TASK number from the TASK= environment variable... yes, i put my 
logs in my FD directory but they could easily go in each node's directory...

  eg:
       Log File: $[FD]\Node$[TASK]\FD.LOG

use of these EVs (Environment Variables) can be extremely useful in a multinode 
environment... the should be able to be used everywhere you have a path or file 
name defined... you can use any EV that you create in your .bat file so you 
might use $[NODE] if you don't like TASK to store the node number...

  set NODE=42

this TASK/NODE variable is what i passed on my FD command line in my .bat 
file... i had one .bat that handled /all/ of my nodes and made prolific use of 
these EVs... i just started each one in its own window with the same .bat 
file...

----- snip -----
  REM run_fd.bat
  if '%1' == '' goto error

  set FD=c:\fd
  set TASK=%1

  rem make sure node's specific directory exists.
  rem create it if it doesn't. eg: c:\fd\node1
  if not exist %FD\%TASK\nul mkdir %FD\NODE%TASK

  :top

  rem start FD with the TASK node number.
  FD %TASK
  rem do errorlevel processing here
  blah blah
  if errorlevel == 10 goto end
  goto top

  :error
  echo you must tell me the node number to use!
  goto end

  :end
  echo run_fd.bat terminates
