/*
* $Log: /Components/Windows/NT/Async/NTEPC/NTEPC.C $
*
* 1 3/05/96 10:16a Stana
* Miniport driver for EPC
* Revision 2.2 1995/10/04 12:54:52 dirkh
* Change loop variable names in GetEpcConfigInfo to be self-documenting
* which fixes bug of not supporting multiple EBI modules on a single EPC/CON.
* Revision 2.1 1995/09/19 18:26:42 dirkh
* Remove unused routines: StartIo, Read, Write, Flush, IoControl.
* Collapse to NtcxSuccess several identical routines (Cleanup, [Query,Set]Info, QueryVolumeInfo).
* Handle shared memory window locking more cleanly.
* Longest timeout interval is 0.1s (instead of 1s).
* Consistent init timeouts: 3s reset, 10/20s BIOS, 5/10s FEP.
* Revision 2.0 1995/09/19 14:56:06 dirkh
* Sort baud rate table.
* Declare baud rate and modem signal tables as constant arrays.
*
* Revision 1.12 1994/12/20 23:45:36 rik
* conditionally compile LargeInteger manipulations.
*
* Revision 1.11 1994/12/09 14:31:10 rik
* #if Int32x32 back to RtlLarge for NT 3.1 release
*
* Revision 1.10 1994/11/28 09:31:38 rik
* Updated conc. images.
* changed RtlLarge math functions to direct 64-bit manipulation.
*
* Revision 1.9 1994/10/10 10:41:03 rik
* Changed READ_REGISTER_USHORT to READ_REGISTER_UCHAR to fix an alignment
* problem on the PowerPC.
*
* Revision 1.8 1994/08/19 09:27:58 rik
* Updated conc. download to handle moving window if necessary.
*
* Revision 1.7 1994/07/31 14:38:02 rik
* Added 200 baud to baud table
*
* Fixed problem with getting line configuration.
*
* Revision 1.6 1994/06/18 12:59:59 rik
* Closed files and freeing memory which wasn't happening before.
* Update DigiLogError msg's to include Line # of error.
*
* Revision 1.5 1994/05/11 13:21:26 rik
* Updated for new build version preprocessing.
*
* Revision 1.4 1994/04/10 14:51:51 rik
* cleanup compiler warnings.
*
* Revision 1.3 1994/02/23 03:34:30 rik
* Changed so the controllers firmware can be downloaded from a binary file.
* This releases some physical memory was just wasted previously.
*
* Also updated so when compiling with a Windows NT OS and tools release greater
* than 528, then pagable code is compiled into the driver. This greatly
* reduced the size of in memory code, especially the hardware specific
* miniports.
*
* Revision 1.2 1994/01/31 13:52:26 rik
* Updated to fix problems with downloading CX conc. images.
* Fixed problem with EBI modules being part of the configuration and
* not allowing the driver to init properly.
*
* Revision 1.1 1994/01/25 19:06:46 rik
* Initial revision
*
