I have a problem with my serial device on Windows, whereas it works fine on
Linux.
It works fine on Linux:
use Device::SerialPort qw( :PARAM :STAT 0.07 );
$PortObj = new Device::SerialPort ($PortName, $quiet, $lockfile) || die "Can't
open $PortName: $!\n$file_exists"; }
I get an error on Windows Vista:
use Win32::SerialPort qw( :PARAM :STAT 0.19 );
$PortObj = new Win32::SerialPort ($PortName, $quiet, $lockfile) || die "Can't
open $PortName: $!\n$file_exists"; }
D:\tmp>.\dvm2000v0.1.11.pl --device="COM4"
=> doesn't claim to be a serial port
at D:\tmp\dvm2000v0.1.11.pl line 404
Can't open COM4: No such file or directory
Same error when using "\\.\COM4" as device name.
When I unplug the cable, the error message "doesn't claim to be a serial port"
is not printed.
About the serial device:
dmesg: SPCP8x5 ttyUSB0: SPCP8x5 converter
USB ID: 04fc:0201 Sunplus Technology Co., Ltd
What is going wrong? What can I check to fix this issue?
