To answer as best I can... The selection of the output file handle 'select($t)' is not needed---now I realize that it is not necessary since '$t->print()' directs output to the file handle (which is the socket). The $t->flush() is an attempt to ensure that the command is sent--I learned this also is not necessary.
Then I get the response (which is buffered and not displayed until another carriage return is sent. Which is the key problem that I'm stuck on).
I can get the link to work by calling my 'SendCR()' Client sub (which merely sends a a "!\n"). So that's my work around, until I can fathom the process. I've been reading and working examples. The work around will do for the rest of the program development...but it's not technically the right answer. (sigh). Thanks for your response.
I don't want anyone to debug my program for me... the previous post asked for working examples... it's difficult to cut out brief parts... sorry that was not enough to relay the problem. It will shine when it shines. The learning curve is the difficult to cross at times. Thanks again, take care.
