I hoping that someone else has had the same problem here.

I have written a script to connect via Perl::Expect using telnet to a Data Track device which is connected to a Meridian voice switch.

The escape sequence to leave the voice session and reenter the Data Track menu is ~@ (tilde followed by an at sign). Works interactively manually - but I cant get it to work via Perl Expect.

Previous problems I have had when sending these type of disconnect signals to other devices is that a trailing carriage return causes the sequence not to be interpreted correctly. This is not the case here.

I have tried:- 

$self->{_exp}->send("$RespCmd");
Where $RespCmd = ~@ or '\x7E\x40' or '\176\100'

Anyone have an idea as to how to identify what might be the issue. I'm told the tracker uses tip for terminal emulation.
