* This DLL contains the user interface for the serial driver.
|
|
* a dialog box to configure the specified COMM port
|
|
* an interface to the control panel (??)
|
|
* functions to load and save default configuration
|
|
*
|
|
* Eventually the 32 bit comm port driver could be moved into here
|
|
* and interfaced to KERNEL32 using the WIN95 or WINNT comm driver interface.
|
|
* This way, different driver DLLS could be written to support other
|
|
* serial interfaces, such as X.25, etc.
|
|
*
|
|
* Basic structure copied from COMCTL32 code.
