[Coco] Coco > internet... OS9 vs NitrOs9

[George Ramsower]

 This is perfectly clear. I have to build a boot disk to Nitros9. 
 I have no problem with this except for the fact that in the past, I have never been able to find a way to access my hard drive. It seems the device descriptors aren't exactly the same. I don't remember right now how this is.  It will take a few days or more for me to get to this project.

 I'll start a new thread on this issue when I get there.

 Thanks, Aaron

  Ok, I will try to explain it :)

  Most of the talk on the list recently has been about using DriveWire
  to connect a CoCo to the internet.  DriveWire is not the only way to
  do that, but it's a pretty neat way to do it.

  DriveWire requires NitrOS-9 to the best of my knowledge.  In fact, in
  developing the upcoming version of DriveWire, Boisy has found some old
  bugs in OS-9 that are only now corrected in NitrOS-9, and also made
  some changes in NitrOS-9 to support things we are doing in DriveWire.
  It may be possible to make these same changes in Microware OS-9, but I
  would imagine it would be a tremendous amount of work and the end
  result would be something basically the same as what NitrOS-9 already
  is.

  DriveWire provides 15 virtual serial ports under NitrOS-9 using a
  single physical port, just the bit banger.  Each of these 15 virtual
  ports has it's own virtual modem, built in to the DriveWire server,
  which allows legacy telecom programs like terminal programs and BBSes
  to be connected to the Internet.  These ports can also be used by new
  applications that communicate with the outside world via TCP/IP.  This
  makes it possible to run a web server, telnet, ftp or an IRC client on
  the Coco, and that's just the beginning.

  Without DriveWire, you can still do a limited amount of connection
  between the outside world and the Coco.  You won't have things like a
  web server or other internet functionality, but you can still make
  telnet connections in and out (run a bbs, etc).  You need a physical
  serial port (6551 and/or bitbanger should work)  for each line, so in
  your case you could theoretically get 4 lines up.  You will also need
  the same number of serial ports on your PC (or multiple PCs) and
  cables between everything.  You will need software to bridge each
  serial port to a TCP socket.  The "Internet Modem" program can do this
  for one port.  I do not know if it is possible to run multiple copies
  of the Internet Modem program on one PC, but you'd need to do
  something like that to have a virtual modem on each serial port.
  There are other programs besides Internet Modem that do this same
  thing, maybe one can be found that supports multiple serial ports more
  easily.

  As mentioned earlier, yet another option for systems without NitrOS-9
  and Drivewire would be a terminal server.  These often have 4,8,16, or
  more serial ports.  Again you will need one serial port on CoCo for
  each line you want to make available.  A terminal server would
  probably work better for incoming connections than for outgoing, since
  it does not include a "virtual modem" type of functionality.  There
  may still be a way to use it to make outbound connections, it just
  won't work like a modem.

  So in a nutshell.. NitrOS-9 + DriveWire gives you 15 lines all with
  internet modem and more using just the bitbanger and one cable.
  Regular OS-9 requires one serial port per line, a PC with the same
  number of serial ports, the same number of serial cables, and then
  some software running on each serial port to do the virtual modem bit.

  Hopefully that makes sense, if not, I can try to answer any specific
  questions you have.
