Ok, thank you guys for the information!

Today i finished the case for my external CMM2 Floppy Drive: Here some Pics:

The next Step is to mount an IDE (40 Pin) Connector on the backside for the CMM2 Connection.

It won't blow off the table anyway. :)
Actually, I think it looks really neat. Your cutting and assembly look very precise.

Good work Vampire05,

It won't be long before we hear the buzzing and sizzling of the floppy....
I remember the excitement when my old Acorn Atom was reading disks with a home-brew disk interface (5 1/4 back then). The 160k back ten was sufficient for 20-50 programs. Good that we have 1.44Mb now with the CMM2.

hi Guys,
i have some problems with the xmodem transfer. here is the full basic file

floppy.bas.zip

the simple commands(dir, type, dump, rmdir, mkdir) works great but the xmodem command did not.

what i do:

i open the serial connection

open "com1:115200, 256, get_floppy_output, 1" as #1

then i send the arduino dos command:

print #1, "receive " + args(2)

and then the xmodem send on cmm2:

xmodem send "floppy.bas", #1

i tried also

xmodem send "floppy.bas",1

xmodem send "floppy.bas"

after longer waiting i see the empty file specified in args(2) is created on the floppy drive with the size 0. The cmm2 says "Remote did not respond".

Any ideas how i can debug this problem?
