Hi there,

I have an application with a CompactLogix processor (L32E) polling a remote site via a 9300-RADKIT modem. I have no problem to connect to the remote site usign a "ATDT" command line in an ASCII string (with block AWA). I have no problem to exchange data from remote site to local PLC.

My problem is: I cannot hang-up the phone line. I tried a "AWT" command via ASCII string with the string "+++", I also tried the commands AHL with a AND mask and OR mask as per the example in the "SCADA" manual from Rockwell Automation. Nothing works.

Can somebody help me on that issue ??

fuzzy logic
The hangup command should be ATH0^M
