Write a string of characters to a serial line and return the number of characters written.
DevSerWriteCharInput: DevVarCharArray
Characters to write
Output: DevLong
Number of characters written
Write N characters to a seria line and return the number of characters written.
DevSerReadStringInput: DevLong
type of read SL_RAW SL_NCHAR SL_LINE
Output: DevString

Output: DevString
response of the device behind the serial line
This method permit to send a request to a device throw the serial line and returns the response of the device. The commands write and read don't return until they have not finished.
DevSerGetNCharInput: DevVoid
no argin
Output: DevLong
number of char available in receiving buffer
Return the number of chars available in receiving buffer
DevSerReadNCharInput: DevLong
number of the caracters to read on the serial line
Output: DevString
pointer to the string read updated
Read a string of N characters from the serial line If there are no characters to be read returns an empty string.
DevSerReadRawInput: DevVoid
no argin
Output: DevString
pointer to the string read updated
read a string from the serialline device in mode raw (no end of string expected, just empty the entire serialline receiving buffer).
DevSerReadLineInput: DevVoid
no argin
Output: DevString
pointer to the string read updated
read a string from the serialline device in mode line (up to and including the character specified by the NewLine property
DevSerFlushInput: DevLong
flush to do 0=input 1=output 2=both
Output: DevVoid
no argout
Win32 method : Flush serial line port according to argin passed.
DevSerSetParameterInput: DevVarLongArray
device parameters in pair
Output: DevVoid
no argout
Set serial line parameters
DevSerSetTimeoutInput: DevShort
Value of the timeout to set
Output: DevVoid
no argout
This command sets the new timeout (in ms).
DevSerSetParityInput: DevShort
The new parity to set.
Output: DevVoid
no argout
Sets the new parity of the serial line. NONE 0 ODD 1 EVEN 3
DevSerSetCharLengthInput: DevShort
The new charlength to set
Output: DevVoid
no argout
Sets the new charlength. 0 = 8 bits 1 = 7 bits 2 = 6 bits 3 = 5 bits
DevSerSetStopbitInput: DevShort
The new stopbit to set
Output: DevVoid
no argout
Sets the new stop bit. 0 = none 1 = one stop 2 = 1.5 stop bit

DevSerReadRetryInput: DevLong
number of reading retries
Output: DevString
pointer to the string read updated
read a string from the serialline device in mode raw (no end of string expected, just empty the entire serialline receiving buffer). If read successfull, read again "nretry" times.
DevSerReadNBinDataInput: DevLong
nb char to read
Output: DevVarCharArray
array of data
Read the specified number of char from the serial line. If the number of caracters is greater than caracters avaiable, this command returns all caracters avaiables. If there are no characters to be read returns an empty array.
