-// TMEXLnk.C - Link module to call on TMEX low-level functions to\r

-// (Requires TMEX 3.11 or newer)\r
-//\r
-// Version: 3.00\r
-//\r
-// History: 1.00 -> 1.01 Return values in owLevel corrected.\r
-// Added function msDelay.\r
-// 1.02 -> 1.03 Add msGettick, always return owLevel success\r
-// to hide adapters (DS9097E) that do not have\r
-// power delivery capabilities.\r
-// 1.03 -> 2.00 Changed 'MLan' to 'ow'. Added support for\r
-// multiple ports.\r
-// 2.10 -> 3.00 Added owReadBitPower and owWriteBytePower\r
