Is there any serial port library?
How can I change /dev/ttyACM0 parameters (baud, handshake, parity, stop bit etc) ?
My tablet is rooted, and i can transfer
data with shell command that;

suShell("chmod 666 /dev/ttyACM0")
suShell("cat /mnt/local/example.txt > /dev/ttyACM0")

Sub suShell (komut As String)
Dim Command, Runner As String
Dim stdout, stderr As StringBuilder
Dim Result As Int
    Runner = File.Combine(File.DirInternalCache, "runner")
    Command = File.Combine(File.DirInternalCache, "command")
    File.WriteString(File.DirInternalCache, "runner", "su < " & Command)
    File.WriteString(File.DirInternalCache, "command", komut & CRLF & "exit") 'Any commands via crlf, and exit at end 
    stdout.Initialize
    stderr.Initialize
    Result = Ph.Shell("sh", Array As String(Runner), stdout, stderr)

End Sub

Have you tried using the new UsbSerial library?

 

[emresensoy]

yes but there is only baudrate option,
i need to communicate with 7data bit, 2 stop bit, even parity and hardware handshake,
how can i set these parameters in usbserial?

 

[emresensoy]

also i want to choose the serial device,

The open source library which is used by UsbSerial only supports setting the buadrate.
