Details:

I am running MXE Octave build 3.8.2-5 installed from http://mxeoctave.osuv.de/
on an Windows 7 64 bit machine. Specifically I am using the portable version.
I have installed the instrument control package 0.2.1

When running sample code for instrument control toolbox I get the following
error, "error: serial: Error opening the interface: Bad file descriptor"

I can see the serial ports in the device manager, but it doesn't seem to
recognize them.



%Code taken from http://wiki.octave.org/Instrument_control_package#Serial

close all
clear all
clc

if (exist("serial") == 3)
    disp("Serial: Supported")
else
    disp("Serial: Unsupported")
endif


# Open default serial port ttyUSB0 in default configuration of 115200, 8-N-1
%s0 = serial() 
# Opens serial port ttyUSB1 with baudrate of 115200 (config defaults to
8-N-1)
%s1 = serial("/dev/ttyUSB1", 115200) 
s1 = serial("COM1", 115200) 

# Flush input and output buffers
srl_flush(s1); 
# Blocking write call, currently only accepts strings
srl_write(s1, "Hello world!") 
# Blocking read call, returns uint8 array of exactly 12 bytes read
data = srl_read(s1, 12)  
# Convert uint8 array to string, 
char(data)



%Output of above code is copied below
%Serial: Supported
%error: serial: Error opening the interface: Bad file descriptor
