MSS User Guide 5: Using the MSS
5-8
Adding Hosts
The host list can include up to 16 host entries in any combination of TCP (raw, Telnet,
and Rlogin) and UDP addresses.
Figure 5-13: Adding Entries to the Host Table for MSS-VIA and MSS4
Local>> CHANGE PORT 1 DEDICATED HOSTLIST
Local>> HOST ADD TCP 192.168.0.10:T
Local>> HOST ADD UDP 192.168.0.14
Local>> LOGOUT PORT 1
Figure 5-14: Adding Entries to the Host Table for MSS100
Local>> CHANGE DEDICATED HOSTLIST
Local>> HOST ADD TCP 192.168.0.10:T
Local>> HOST ADD UDP 192.168.0.14
In the example, the UDP host entry is actually a broadcast IP address. Data is sent to all
hosts on that particular subnet.
Removing Hosts
To remove an entry from the host table, use the Show Hostlist command to find out its
entry number, and then use the Host Delete command to delete it.
Figure 5-15: Removing Entries from the Host Table
Local>> SHOW HOSTLIST
1 192.168.0.10
2 192.168.0.12
3 192.168.0.14
Local>> HOST DELETE 2
Modem Emulation Mode
In modem emulation mode, the MSS presents a modem interface to the attached serial
device: it accepts AT-style modem commands and handles the modem signals correctly.
Normally there is a modem connected to a PC and a modem connected to some other
remote machine. A user must dial from his PC to the remote machine and accumulate
phone charges for each connection. With the MSS in modem mode, you can replace your
modems with MSS device servers and use an Ethernet connection instead of a phone
call, all without having to change communications applications. You can then connect to
any remote machine that has an MSS without making potentially-expensive phone calls.
Note: If the MSS is in modem emulation mode and the serial port is idle, the MSS can
still accept network TCP connections to the serial port.
To use modem mode, enable modem emulation and set your MSS for Autostart using A
as the autostart character. This triggers the MSS to enter modem mode when it
encounters a modem-style AT command.
