TCP/IP and Telnet from Clipper

[Bozz]

One of my customers is going from serial RS232 dumb terminals/terminal emulators on PC's to a TCP/IP based Telnet infrastructure. My Clipper 5.01a/Nantucket tools II based software communicates with their system via a
serial port that is due not to exist soon. Is anybody aware of a way of "talking Telnet" from Clipper?

Something I will do on occasion in this case is write or contract out a small windows applet in VB, JAVA, C++, C# or another language and use it to pass the information thru TCP/IP. So basically I just call the formless windows application to handle the data transmissions. I will look thru our libraries up at work and see if I see anythign that may help you out other than that.

Thanks Richard,

I suppose that it might be possible to shell out and batch run Telnet. I've done a similar thing with Blat for sending e-mails from Clipper. In a batch file one progran prepares another batch file, calls the batch file to do the sending and then another program analyses the log file. The only worry is that what I need to do is very &quot;real time&quot;. What I actually do is send a patient hospital number to a host system and this returns the demographics for that patient, usuall taking <2secs. Ian Boys

Well, Ian,

You could get some of the new Clipper compilers, like XBase++ or Harbour to run your app (I guess it has outgrown 'simple') in a Windows (32 bit) or Unix environment and they both have at least some support for TCP/IP comm's, 'cause they interface to every windows DLL or Unix systemcall you could ever need. At the same time giving you app a big rewrite.....:-( and speed-kick ;-)
HTH, TonHu
