I may be wrong; however, from your description I would suspect that the system
in question is either a PDP11 or VAX running almost any of the DEC proprietary
operating systems--IAS, RSX, RSTS/E, TSX, VMS, etc.  Standard handling of an
<ESC> by the terminal driver is to terminate the current read when received.
The remainder of the escape sequence will be the inserted as the first bytes in
the next buffer.  If this is the case, the fault lies in the implementation of
the TELNET client software which is not handling escape sequences correctly in
this particular environment.
