SerialPort
Cobra's support for serial ports comes through the .NET standard library. See:
- System.IO.SerialPort
- SerialPort (RS-232 Serial COM Port) in C# .NET

Example
The following example comes from SerialPort (RS-232 Serial COM Port) in C# .NET, converted to Cobra.
use System.IO.Ports use System.Windows.Forms class SerPort shared # Instantiate the communications port with some basic settings var port = SerialPort("COM1", 9600, Parity.None, 8, StopBits.One) def main is shared print 'serialPorts:' for s in SerialPort.getPortNames print s .sendSampleData #.rcvSampleData def sendSampleData is shared # Open the port for communications try .port.open catch ioe as IOException print ioe.message CobraCore.exit(1) # Write a string .port.write("Hello World") # Write a set of bytes .port.write(@[0x0A_u8, 0xE2_u8, 0xFF_u8], 0, 3) # Close the port .port.close def rcvSampleData is shared print "Incoming Data:" # Attach a method to be called when there is data waiting in the port's buffer # C#: port.DataReceived += newSerialDataReceivedEventHandler( port_DataReceived ) listen .port.dataReceived, SerialDataReceivedEventHandler(ref .port_DataReceived ) # Begin communications .port.open # Enter an application loop to keep this thread alive - GUI program - otherwise use a reader Thread Application.run def port_DataReceived(sender as Object, e as SerialDataReceivedEventArgs) is shared # Show all the incoming data in the port's buffer print .port.readExisting
