Changes in version 3.5.5
------------------------
1) Patched 5980: RealPort keep-alives were being sent out on Telnet
                 connections, corrupting the Telnet data stream.  The
                 cause of this problem has not been found. However we
                 patched the firmware so that it will detect and correct
                 the condition.

Changes in version 3.5.4
------------------------
1) Fixed 5370 : problems with 'set auth login='.  Caused by killing a non 
                logged in process which shows up as a null pointer error.
                Removed possibility of pointer becoming NULL.

2) Fixed 5429:  portserver telnet daemon on port 23 starts to immediately
                disconnect. Caused by memory management problem where 
                buffers are not released.

3) Fixed 5721:  auth table corruption caused when the 17th reverse telnet
                session attaches. Caused by using 17th entry slot as 
                temporary storage and getting overwritten.


Changes in version 3.5.3
------------------------
1) Fixed 5219: Binary option does not work with telnet


Changes in version 3.5.2
------------------------
1) Add a second method to assigning the MAC Address in MFG: the 
first 6 digits are hard coded to be 00409D while the last six 
digits are accepted sequentially without the colon separator.  

Note: The first method of specifying the full 12
digits with the colon separator is still valid.
