How to set up TS4 for "telnet ipaddr port#" to connect

I have the Digi PortServer TS4, connected to the ethernet, need to connect using "telnet "… there is a 3 wire device connected to each port.

I need a direct conection, 9600 8N1, No-flow control, no login, no local echo… just a clear open connection

SunStation-> TCP/IP -> Ethernet -> Portserver -> Async Rs232 port -> Async 3 wire Device.

An example config would be great…

thx,
sw

from the ProtServer TS command line
#>set port ra=1-4 dev=prn
#>set logins verbose=off ra=1-4
reboot portserver
#>b a=r
Now you should be able to connect to a port
#telent ip-of_the_ts 2001 (for port 1, 2002 for port 2 etc)
