I am wondering how to communicate via the serial port under Windows7. Has someone a tipp ?
I'm not sure which framework you're using, but as I remember, with cygwin the COMn devices are available as /dev/ttySn .. though, it was a few Santa Clauses ago, so I might remember it wrong. Perhaps Google is your friend?
OK - Thanks, you are right, Google ;) I just found this on github:
//https://github.com/ryuo/newlisp-serial-port
An on the newLISP site under modules : //http://www.newlisp.org/modules/
That module is not finished, but it may be usable from C. I forget what state I left it in. I do remember it lacks a newLISP interface.
