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. 


Changes in version 3.5.0
------------------------
1) Fix for UART detection on the PortServer 8.

2) Fix Telnet session hang when PortServer's IP address is changed (PR#173).
Note: IP Address change is still effective immediately.

3) Fix problem where requesting getty without loging in using the settings "set
login=off" and "set passwd=off" resulted in "Error #43: Access to this port is
denied" (PR#2785).

4) Fix PortServer hang when user executes a "send brk" via telnet (PR#3036).

5) Fix PortServer hang when the network is flooded with heavy broadcast traffic
(PR#3036).

6) Add option "set port dev=rp" to eliminate confusion when using realport
(PR#3006).  Note: "set port dev=rp" is functionally equivalent to "set port
dev=prn".

7) Documentation notes: PortServer does not support the Character-based MIB
(RFC1316) nor the RS232-like MIB (RFC1317). PortServer Manual P/N 90028700B,
incorrectly said the functions were supported.
