Hallo, guys, nice to meet you. Big thanks for nodejs!
I do nodejs with USB 3G modems via its application interface on COM ports.
On windows (XP, 7) openning COM almost always works no matter if there is
device in USB or no:
> require('fs').openSync('\\\\.\\COM8', "w+")
3
>
sometimes it gets this: [1].
One day i've got such thing too on my working laptop, which was fine
before. Reboot helped (win7, many sleeps and hibernates).
But on other PCs nothing helps (node 7,8,9 32 or 64 bit, win7, XP,
reboots), though [1] was there from the very beginning.
How this can be debugged?
Thanks!
[1] other computer:
> require('fs').openSync('\\\\.\\COM10', "w+")
Error: OK, success '\\.\COM10'
