This sounds like an upgrade of an existing site that WAS working but works 
no longer.  When debugging these things, it's often helpful to do some line 
traces: STR, END, PRT, DLTCMNTRC as well as TRCICF.  Also, look at STRITF 
to get a quick glance at the data that is coming in.  You should also be 
able to use a PC with Procomm or Crosstalk to log the data.  Carefully 
check the line connections - you'd be surprised at how often a bad cable is 
the culprit after a move!  Also, carefully check the line/controller/device 
descriptions.  Especially important are baud, parity and word length.  If 
there are modems involved, were they powered off/on during the upgrade? 
Sometimes you need to set a modem's "initialisation strings" after the 
modem gets powered off - these can be finicky, and the modem manual can be 
of some (small) help.  The key is to isolate what changed from what stayed 
the same.   As a last resort, recompile the ICF files and HLL programs with 
the latest batch of PTFs installed.
