[Coco] Um3.init help needed

[Bill Pierce]

I'll check in with Michael Knudson on the serial mouse thing. Since he wrote itm I'm sure he can give us the format for um3.init. I also have the sources and will look through the 110 various asm and C source files to see if I can locate any info on it. As for the memory, I'm pretty sure it doesn't make use of any extra memory as the modules are loaded at once and hog quite a bit of memory. The music file itself is stored in a hidden hi-res graphics screen and I/o is done with the get/put buffers. This is eating up quite a bit of memory by itself. In both ubox3 and ultimuse3, if you select the "serial" midi option, they mess with the bit-banger. The /MIDI driver for drivewire resolves this with proper interrupts so midi doesn't "hog" it.

Hope this was some help, I'll check on the serial mouse thing.

Who perchance is the resident expert on umuse3, as downloadable from RTSI?
I cannot locate a format spec for /dd/sys/um3.init, and my seriel mouse is 
ot being detected or used by ubox3.  I have scanned the about 75 pages of 
ocs included in that package, but it seems as if it is supposedly self 
enerated, which obviously isn't possible if the mouse is not detected at 
ll.
The mouse data packet is working as I have a little debug program that 
isplays the l51defs portion of memory, and mouse motions and buttons are 
eing updated when I move the mouse or push a button.
Also, its defaults seem to be interfering with the bit banger as dw is 
ssentially dead.  But a reboot, restart of ubox3 and a / to select 
MIDI.dd, and ubox3 now plays music on my linux boxes speakers, provided I 
se dw4's java synth, and not my sound cards synth.  Probably some diff in 
he hardware addressing I suppose.  I have a /dev/midi, but it doesn't show 
n the dwGUI menu's.
Anyway, if someone can decode the /dd/sys/um3.init file format for me, or 
M me a copy of yours so I could see whats in it, I'd be thankful.
My current boot I believe is running out of memory to run umuse3, it starts 
o draw its screen, then does an exit, error 37, missing right ).  That has 
o be an OOM error because smap says I only have 5k system free after a 
eboot.  Its a 2 megabyte coco3 though.
Thanks & Cheers, Gene
