-The ACM driver works with modems and ISDN TAs that use the USB Abstract
-Control Model standard. 
-
-****************************
-Test it:
-Watch out, the driver is not stable and tested. Sync often, make backups,
-most importand: don't blame me...
-
-Create device files:
-mknod /dev/ttyACM0 c 166 0
-mknod /dev/ttyACM1 c 166 1
-mknod /dev/ttyACM2 c 166 2
-mknod /dev/ttyACM3 c 166 3
-Compile a kernel with support for your host controller (uhci only for now!)
-and support for ACM. Boot this kernel. If you connect your device to the
-USB bus you should see messages like the following:
-
-Jul 19 20:14:29 office kernel: USB new device connect, assigned device number 1
-Jul 19 20:14:29 office kernel: Found 02:09

-
-Watch out for the line:
-Jul 19 20:14:29 office kernel: USB new device connect, assigned device number 1
-and the line:
-Jul 19 20:14:29 office kernel: USB ACM found
-These two lines show that the device was seen by the usb host controller and
-then recognized by the acm driver as a valid device.
-
-If you use a terminal emulation software like minicom with /dev/ttyACM0 you
-should be able to send AT commands to your device and get responses. I've 
-been able to do zmodem downloads to another pc. However downloads from one
-ISDN TA to another ISDN TA connected to the same PC didn't work. Don't
-know why. Flow control is not finised after all and i'd guess there might
-be problems on heavily loades PCs. I also did some tests with ppp but i'm
-not finised with this. There might be a chance to get it working. However
-i'd like to know if your device is recognized as an ACM device. I'm also
-interested if the thing is stable or if it crashes.
-(should i say how it crases?)
-
-You should be able to add and remove devices from the bus. The driver will
-always try to fill up unused ttys. This means if you hotplug devices their
-order may have changed after reboot. This is not the behaviour Linus liked
-to see but it's ok for now. (I hope ;-)
-
-Please report your experiences to me:

-
-***************************
-I've tested it with:
-3Com ISDN Pro TA.
-
-It should work with (That means i know these devices conform to ACM):
-3Com Office Connect Modem
-3Com Sportster USB (I think that's what it's called)
-
-***************************
-Many thanks to 3Com which did not only support me with hardware but also
-with technical support in USB questions. They also allowed me to do tests in
-their lab. Great!
-
-***************************
-Known bugs:
-Flow control not tested (likely not to work)
-Some tty function calls not implemented (putchar, etc...)
-Huge amounts of debug output (compile in [*] Magic SysRq key and press ALT+PRTSCR+0 )
-Not all mem is freed at close (need terminate irq in hcd)
-
-***************************
-Have fun,
