Seeing the need to combine wireless connectivity and telnet terminal emulation, MIRROR 
5250 Emulator, also known as CipherNet-5250, is designed to provide telnet terminal 
emulation on the 8000/8300/8400/8500 Series Mobile Computers, which are capable of 
802.11b/g or GPRS connectivity. 
The software, consisting of CipherNet programs (.exe) and the associated runtime (.shx), 
is designed for the users to develop custom telnet sessions for the use with the terminal 
emulation runtime preloaded on the mobile computers, without spending time writing 
any program code. Each of the mobile computers is a telnet client that allows the user to 
connect to a host computer, such as an IBM AS/400 server that supports 5250 emulation, 
and make use of the applications running on it. Thus, the mobile computer works as an 
input device to a host computer, and the data collected or input will be sent back to the 
host computer. On the other hand, the mobile computer works as an output device as 
well because it can display data coming in from the host. Based on the nature that the 
screen size of the mobile computer is smaller than that of an actual terminal, CipherNet 
programs provide a number of unique features for reformatting host screens. 
This manual serves to provide comprehensive understanding of MIRROR 5250 Emulator, 
and helps start a telnet session running host applications. We recommend that you read 
the document thoroughly before use and keep it at hand for quick reference.     
Thank you for choosing CipherLab products!
