Thank you for your quick response.
It's just simple python code. I'm not sure if flow control is correct.
I also used gtkterm and tried by every option. I'm new at usbserial
devices. How to know how should it be?
import time
import serial
import sys
ser = serial.Serial(
port='/dev/ttyUSB0',
baudrate=4800,
parity=serial.PARITY_ODD,
stopbits=serial.STOPBITS_ONE,
bytesize=serial.EIGHTBITS,
# timeout=0
)
# RTS 0 DTR 1. not sure it's correct one. I tried by reverse.
ser.setRTS(False)
ser.setDTR(True)
print ser.isOpen()
ON="\x1B\x5D"
ser.write(ON)
ser.flushOutput()
print "after write"
# read = ser.read()
# sys.stdout.write("RECEIVED:" + read + "\n")
ser.close()

Hello
Hope you guys are doing great.
I've got problem with pl2303 Linux driver. In a nutshell, my mission is to
control magnetic card reader/writer with PL-2303 XA / HXA chip from the
Linux. I'm using Ubuntu 14.04(kernel version: 3.13.0-39-generic). Everything
is going fine. Giving no errors. Writing data via usb-serial seems to work.
But the device is not receiving data. If that issue familiar with you,
please give me advice.
How exactly are you "writing data"? And have you set up flow control
properly?
thanks,
