UDF for commg.dll
V1.0 Replaces mgcomm.au3
#ce
Const $sUDFVersion = 'CommMG.au3 V2.8'
Global $mgdebug = False
#cs
Version 2.1.1 Added missing declarations which caused problems in scripts using Opt("MustDeclareVars",1) - thanks to Hannes
Version 2.1 Thanks to jps1x2 for the read/send bte array incentive and testing.
Version 2.0.2 beta changed readbytearray so returns no of bytes read
Version 2.0.1 beta
added _CommSendByteArray and _CommReadByteArray
Version 2.0 - added _CommSwitch. Can now use up to 4 ports.
Version 2.2 - add rts, dtr to setport
added option for flow control = NONE to _CommSetPort
version 2.3 use commg.dll v2.3 which allows any baud rate up to 256000.
Version 2.4 added setTimeouts, SetXonXoffProperties
Version 2.5 add _CommsetTimeouts, _CommSetXonXoffProperties
Version 2.6 added _CommSetRTS, _CommSetDTR
change switch so up to 50 com ports can be open at a time
Version 2.7 added _CommSetDllPath
Version 2.8 17th April 2010
add GetLineStates for CTS, DSR, Ring Indicator and DCD
Corrected return of functions _CommSetRTS and _CommSetDTR to be -1 on error
Version 2.81 add sleep(20) in CommGetLine to reduce CPU usage. Thanks to jimg.
Version 2.82 Correct error in _ComSetPort which could prevent _CommSetDllPath working.

;=========== _CommSetTimeouts ========================================================================================================
; Description: Sets the timeouts for the current channel
;Parameters - ReadInt - maximum time allowed to elapse between the arrival of two characters
; - ReadMult - multiplier used to calculate the total timeout period for read operations.
; For each read operation, this value is multiplied by the requested number of bytes to be read.
; - ReadConst - constant used to calculate the total timeout period for read operations.
; For each read operation, this value is added to the product of the ReadMultiplier member and the requested number of bytes.
; - WriteMult - multiplier used to calculate the total timeout period for write operations.
; For each write operation, this value is multiplied by the number of bytes to be written.
; - WriteConst - constant used to calculate the total time-out period for write operations.
; For each write operation, this value is added to the product of the WriteMultiplier member and the number of bytes to be written.
; if a parameter is set to 0 it means that timeout will not be used. All values are at zero when a port is opened.
; Return 1 on success
; 0 on failure
