Has anyone tried using one of the PC remote control software packages (such as CloseUp or Carbon Copy) over the Internet? The idea would be to connect the controlling PC to a terminal server, Telnet to a milking machine, and then to the controlled PC. Does anyone know authoritatively if such a thing is possible? Thanks in advance. --Mike

My gut feeling is that you're probably going to have to find a remote control package that contains support for the INT14 interface. FTP Software's PC/TCP allows you to TELNET to some host, and then invoke a terminal-emulation package that supports INT14, and you get everything you'd get from a 9600 bps dialup connection, with the exception of session initiation. You have to TELNET, then fire up the emulator, and once connected, you can't TELNET somewhere else without starting the whole process over again. TELNETing to a router would alleviate this last sticking point. If you find a "Carbon Copy", "Close UP",-type thing that supports INT14, I would also be interested in hearing about it. I looked last year, and couldn't find anything.

>Has anyone tried using one of the PC remote control software packages >(such as CloseUp or Carbon Copy) over the Internet? Yes, (though only over very little pieces). Get two PCs running the NetBIOS LAN version of CloseUP/Carbon Copy and a vendor of NetBIOS over TCP/IP which supports M/P-node or extended B-node services. Stir gently and hope the delay characteristics don't upset the PC software too badly.... >...The idea would be to connect the controlling PC to a terminal server, >Telnet to a milking machine, and then to the controlled PC.... ..Sorry, no telnet allowed if you really want remote control -- you need CloseUP/Carbon Copy type software running over TCP/IP at both ends. If you fit Stanford's licensing characteristics you can get their VT100 emulation telnet server for DOS, but that really is a very different beast. >Does anyone know authoritatively if such a thing is possible? Yes. Though as I mentioned, your mileage will vary. enjoy, leo j mclaughlin iii ljm@ftp.com

Can someone name some that aren't? TCP/IP protocol implementations that aren't internetworkable (such as B-mode NETBIOS) seem like almost a contradiction in terms to me. > >...The idea would be to connect the controlling PC to a terminal server, > >Telnet to a milking machine, and then to the controlled PC.... > > ..Sorry, no telnet allowed if you really want remote control -- you need > CloseUP/Carbon Copy type software running over TCP/IP at both ends.

I understand that PC Anywhere allows remote control of character-based applications with the other end being a VT100, rather than another copy of PC Anywhere. This would seem to allow the milking machine connected to controlled PC idea to work. Has anyone actually tried it?

PC Anywhere will allow anyone of aprox. 50 terminal types to access it. That is it best feature above any of the other remote control packages. I have gotten it working across various netbios emulatos. I wouldn't see a problem with NetBIOS over TCP/IP.

I've read the RFC's, but I'm not clear as to which services you're depending on. (Especially in the extended B-node case.)

B-node dependent services/implementations will not operate across an extended LAN which merely routes. Bridging (perhaps via bridging routers ) would be required to support this functionality. RFCs 1001/1002 do include mechanisms to support NetBIOS across routed LANs via M/P-node support, but: 1) either the potential user market is not [yet :-)] large enough for the vendor community to merit the development effort, 2) NetBIOS-based LANs are typically being "bridged", or 3) there are enough unresolved issues in the RFCs to make interoperability between vendors a sticky issue; that to the best of my knowledge, the available M/P-node based product offerings are underwhelming or virtually non-existant. Maybe the problem stems from all three. I'm sure that's more than you asked for.... oh well. Steve -- Steven W.
