Subject: Net::Telnet->getlines() not returning any data

Hi, Based on the documentation, getlines gets all data currently in the buffer. This isn't working in my environment which is the following: Net::Telnet->Terminal Concentrator->Serial console of fibre channel switch In order to test this functionality, I am logged into the same console from Net::Telnet and from my laptop. I can run commands on the console from my laptop which Net::Telnet should read with getlines(). The test steps to reproduce the issue are as follows: 1. Open up a connection to the terminal concentrator from my laptop 2. Open up a connection to the terminal concentrator via Net::Telnet and join the same session used by the laptop 3. Run a script to produce output on the console (see output below): 4. Run $session->getline() to prove there is data in the buffer: DB<11> x $session->getline() 0 "B5300_044_141:FID128:root> counter=0\cH\cH\cH\cH\cH\cH\cH\cH\cHwhile true; do echo \"iteration \$counter - testing line\cMe length of 60 characters........\"; let counter=counter+1; done\cJ" 5. Run $session->getlines() and nothing is returned: DB<12> x $session->getlines() empty array 6. Furthermore, now the buffer is empty as getline doesn't return anything: DB<13> x $session->getline() empty array If I run the same steps 1-4, but at step 5 I do this: while (my $line = $session->getline()) { print "$line" } I do get back all the data as you can see here (only partial data, but you can see it works): DB<15> x while (my $line = $session->getline()) { print "$line" } iteration 0 - testing line length of 60 characters........ iteration 1 - testing line length of 60 characters........ iteration 2 - testing line length of 60 characters........ iteration 3 - testing line length of 60 characters........ iteration 4 - testing line length of 60 characters........ Thanks much for your time!
