SignatureKnute Johnson email s/nospam/knute/ here is a smslib maybe you can find some useful thing here: http://smslib.sourceforge.net/ > How can I communicate with COM1 port using JAVA application. I was looking into this today. Sun created the Java Communications API (javax.comm) for this, at one point they supported a javax.comm implementation for Windows but now they only support Solaris and Linux (and maybe some other Unix variants). So if you want to use Sun's javax.comm on Windows you need to track down an old version of javax.comm Jar and DLL. Unsatisfactory. You can open COM1: using an ordinary file I/O. Unfortunately you can't read and write concurrently so this is of limited use. <http://www.rgagnon.com/javadetails/java-0062.html> Doubtless there are commercial products you can buy that provide Java with the capability to communicate with COM1. > Is there a good link for that please <http://www.google.com/> :-) ISTR Roedy Green's Java website has some stuff on SerialPorts >> How can I communicate with COM1 port using JAVA application. > [quoted text clipped - 18 lines] > > ISTR Roedy Green's Java website has some stuff on SerialPorts I do a lot of serial stuff and the Java Comm API is still the only library that works. With the situation the way it is I am really tempted to write my own JNI library.
