There was some recent discussion about serial ports and Perl.

But I did not see any resolution.
Did anyone end up porting either Win32::SerialPort or Win32API::CommPort
as Reini suggested?
I need to talk to a thermometer via a serial link. The protocol is not
very complex.
Could I just use a system call to stty to set the baudrate and then pipe
the thermometer comand to /dev/ttyS0 and read the response from
/dev/ttyS0 using file handles?
Reini - you suggested adding cygwin support for Device::SerialPort would
be the easiest route. Do you still recommend this?
Sure.
I am not very
familiar with Windows API library, but could I just use Win32::API to
call some already existing entry points in Windows?
Uaing .xs is usually easier than using an FFI i.e. Win32::API.
And Win32::API doesn't compile out of the box on cygwin.
I have a stripped version without callback support at my site, but using
xs is better.
If you really want an FFI I recommend FFI over Win32::API by far.
