The API for serialui.dll is not documented, but
native printui.dll expects FALSE with ERROR_CANCEL,
when the Dialog is canceled, so i started the testsuite.
("serialui.dll" on win9x is a 16-Bit (NE) dll.)
As a first Test-Result, the native DLL returns the
win32 errorcode for drvGetDefaultCommConfigA/W
Our serialui.dll need more fixes to match to the
native version (NT):
- the Devicename must be searched as a Data in
HKLM\HARDWARE\DEVICEMAP\SERIALCOMM\
(Example: Entry "\Device\Serial0" with data "COM1")
- the default configuration is stored as Data in
"win.ini" [Ports] (Example: "COM1:"="38400,n,8,1,p")
=>HKLM\Software\Microsoft\Windows NT\CurrentVersion\Ports
(Example: Entry "COM1:" with data "38400,n,8,1,p")
- The native Dialog has "Flow-Control" as latest Item
- The native Dialog is a single-page property-sheet
Changelog:
- serialui: Fix returntype for drvGetDefaultCommConfig
