[Coco] DW4 error

Mon Jun 30 19:11:33 EDT 2014

It may be generally helpful to point out that when using DriveWire, as
far as I can remember, there is no time when you will ever specify
115.2k baud anywhere.  So, any time you seem to need to set something
to 115.2k or specify 115.2k in some way, you may want to consider it a
clue that you're probably on the wrong track :)

To connect to the console using headless mode, you use telnet.  The
address is that of the machine running the DW server, and the port is
the value specified for TermPort in your configuration.

Of all the disks available premade for NitrOS9, headless is the one
flavor that does require an additional setting (TermPort) and does not
just work out of the box, and also the only one that doesn't let you
just start using the CoCo in the traditional way.  Even more
unfortunately, at this time it appears that headless mode is just
broken, at least it is in the server I am running here.  It always was
a bit of a hacky, experimental thing.  It might only be a problem with
the slightly different server I'm running, it might be a problem with
the latest disk build, or maybe even because I can only test via the
becker flavor, but it seem most likely to be a server side issue to
me.

I highly recommend you start with basically any other disk.  There are
lots of games and applications available on the nitros9 page or from
other repositories, and pretty much any one of them is going to be
easier to use.
