Thanks for the clarifications/suggestions Bill, Alex. Alex you say: "The data from there is fed to J but the polling application is in VB6."
Was that in real time or for subsequent processing? If in real time, what mechanism did you use for the feed? I did consider writing a serial-to-socket bridge, but I'm trying to avoid too much low-level stuff distracting me from the main task. I think I'll try for opening the port as a file for now and see how that goes. I actually managed to find some likely looking code on this site, ( http://www.jsoftware.com/svn/base/trunk/packages/misc/telecom.ijs ) but it claims to work for W95 only and I do not not enough of CE's quirks (or J's for that matter) to know what problem to anticipate. Perhaps just opening a DLL might be a better idea. Thanks anyway gents! I'm trying to avoid using Java or C++, especially since processing GPS position data would be a brilliant job for J, but sometimes it just ain't easy (to avoid, that is ;) ) On Fri, 2010-11-05 at 13:25 +0800, Alex Rufon wrote: > J can actually call an OCX/ActiveX control directly but I don't know how it > would work out for you on WinCE. > > I guess googling for "file open COM1" would help out. :) > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of bill lam > Sent: Friday, November 05, 2010 10:36 AM > To: [email protected] > Subject: Re: [Jprogramming] Accessing the serial port > > There is no inbuilt support for serial port in J.
