Configuration Example when the Router is Located at the Commercial
Client Side in TCP/IP Connection Mode
I. Networking Requirements
Three POS terminals access the 3Com Router series located at the commercial

III. Configuration Procedures
1 Configure Router A
a Start the POS access server.
[RouterA] pos-server enable
b Configure the POS application to destination UNIX host in TCP/IP connection
mode.
[RouterA] pos-server app tcp 0 10.1.1.1 9010
c Configure POS default multi-application mapping table (to map the packet
which cannot be matched with any application to the application).
[RouterA] pos-server map default 0
d Configure POS access interface 0.
[RouterA] interface async 0
[RouterA-Async0] undo modem
[RouterA-Async0] flow-control none
[RouterA-Async0] undo detect dsr-dtr
[RouterA-Async0] async mode pos 1
e Configure POS access interface 1.
