Hi,
I have found that the serial port doesn't get opened sometimes. Here's what
I do:
import serial
ser = serial.Serial()
ser.port = 0
ser.baudrate = 9600
ser.timeout = 1
ser.open()
You can see if the port is open by printing the serial object. In your code
you'll use:
print ser
one of the parameters is open= True (or False)
By explicitly setting the serial object properties it always works for me.

Hello,
I need to be able to send some information through my computer's serial
port. I am using python version 2.6, the pyserial 1.21 module, and the pywin
module. My code seems to be sending info somewhere, because any print
statement I add after the import serial command doesn't show up in my
terminal window. However, the device connected to my serial port doesn't
seem to be registering any received information. I want to send the string
"FREQ 720 MHz."
If anyone could help me out with this code, it would be greatly appreciated:
import serial
ser = serial.Serial(0) #if port has specific name, use: ser =
serial.Serial('portName', 19200, timeout=0)
print ser.portstr #should tell you what specific port was used
ser.write('FREQ 720 MHz')
ser.close()
Thanks,
Dan
