Have you looked at Device::SerialPort? It claims to have an "identical" interface as that of Win32::SerialPort, but I noticed that it has pulse methods for break (and other RS-232 signals).	[reply]

I'm working from my poor old memory here, but I believe if you drop the baud to 0 for 250 milliseconds, that's a "break signal". Or maybe you just need to send NUL characters for 250 milliseconds. Something like that. duff	[reply]

I have not done this, but there is win32::serialport, it might be a good place to start.	[reply]

I had already perused through that; I didn't find any methods that would allow for me to send a break signal. Of course if there is such a method, I may have missed it.	[reply]

After looking further, it appears that Win32API::CommPort, does what you want. Hope that this helps.	[reply]

Yep it sure was... I ended up using "Win32::SerialPort::break_active('Y');". One dumb question though... What does the param do and what are its valid values? Thx to all for the help.	[reply]
