This is just a bit of an update.
I have got Win32::SerialPort working, at least a limited capacity.
After taking a look at the source for it, I discovered that this module
is actually just straight Perl, and it relies on Win32::API. I have
already been using /Reini's cut down version of this for some time, and
so I thought this might work. And it does, at least for the simple
functions.
ie I can set the baud rates, parity etc. Write a few bytes and read them
back after waiting enough time for the external device to reply. This
functionality is actually all I needed to read my precision thermometer.
Since Reini's Win32:API module does not support call backs any
Win32::SerialPort functions that utilise the call backs will not work. I
have not had the chance to delve into exactly what functions that is
yet. I plan to look further into that, but I have limited time to devote
to this - especially now main goal is achieved.
Regards,
Jason
ps. I was never able to get the /dev/com1 or /dev/ttyS1 devices working.
I expected that I would be able to echo commands into /dev/com1 and cat
replies from it.
