Glenn, See if this is of any value. I haven't checked the released version lately, so this may only be in head at this time. But do a CVS check out and compile of 'HEAD'. In there you will find a program called "emcrsh" (in bin). It basically supports the same functions as emcsh only over a telnet session.
To use it with an existing configuration and GUI, in the configuration you are using, simply add "loadusr emcrsh" to the end of "core_servo.hal" or "core_stepper.hal" for example. To use it in place of any GUI, copy bin/emcrsh over bin/emcsh, and in the ini file set "display" to "tkemc". Then emcrsh will run in place of any GUI. Once it is running you can open a telnet session from the local machine as follows: telnet localhost 5007 Or from a remote machine by: telnet <EMC computer IP or DNS address> 5007 This will establish a telnet session with EMC. Enter 'help' or 'help <command>' to show all of the commands which are supported. Some important ones are: Hello <password> <client name> <version> Example: hello EMC emcuser 1.0 The default password is 'EMC', the client name can be anything, but I typically use the network name of the computer establishing the telnet session, and the only version which currently exists is '1.0'. A successful hello exchange is required before emcrsh will respond to any commands other than "help" and "quit". This will allow you to "get" (see "help get") information from EMC. By default, 'echo' is on, so the first thing you will probably want to do is: set echo off Also, when manually entering commands through telnet, you can get more meaningful error messages by turning verbose on, as follows: set verbose on If you want to change any EMC values, then you must "enable" the session as the session in control as follows: set enable <password> Example: set enable EMCTOO Where 'EMCTOO' is the default enable password. Emcrsh supports multiple simultaneous connections, but only allows one to be enabled for control at any given time. A successful enable will disable any other session having control. Note: It does not affect any of the GUIs specified by "display" in the ini files and does not take control away from them, only other telnet sessions. Let me know if that is of any help.
