Alan, In addition to what Stephen said, see if emcrsh does what you want. Take any one of the sim configurations (tkemc is a good one) and add: loadusr emcrsh to one of the hal files (servo_sim.hal for example)
Run EMC, then open a terminal session and enter: telnet localhost 5007 After it connects, type help. To establish a session with EMC, enter: Hello EMC client 1.0 To get rid of the command echo, enter: Set echo off To command the machine, enable the session with: Set enable EMCTOO Alternatively, you can run from another computer over the network by entering: telnet <DNS or IP address> 5007 Your program just needs to send and process the same commands as you type into the telnet session. So long as you write your application from the interface specification, i.e. specifically by not borrowing any of the code from the server side, there should not be any GPL implications. Well on this specific interface anyway. You can also find the interface definition here in the source code: http://cvs.linuxcnc.org/cvs/emc2/src/emc/usr_intf/emcrsh.cc?rev=1.10;content -type=text%2Fplain Scroll down one page. I need to put this into a wiki page. BTW, I just checked in an update enhancing options that can be specified on the command line. To use these, you will need to build from source until the next release. HTH, Eric I want to connect directly to emc from some software I am developing. So far my software generates G codes but I want to cut out that stage. This is out of interest and in the spirit of investigation. By the way I would like to know the easier ways again out of curiosity.
