[Coco] Eureka! I'm Running My Coco 3 with Drivewire 4 Server Finally! or I Found a Bug in HDBDOS v1.4 DW4 Coco 3!

[Aaron Wolfe]

I'm looking at

http://sourceforge.net/p/nitros9/code/ci/default/tree/level1/modules/

and it seems there are 3 pairs of read/write sub modules for dw.  One
is simply called dwread/dwwrite... this is the standard 115.2 on coco
3 module.
then there is the dwrd/dwwrmess pair for use with MESS and John L.'s
mess patch (this is kind of outdated, should really be changed to use
Becker port like VCC and XRoar do).  Then there is a pair called
dw4read/dw4write... these are the 230k mode drivers. Their label being
"dw4" is consistent with the 230k HDBDOS ROM being labeled "dw4"...
maybe there is some logic here and I'm just not aware or have
forgotten :)
