Configuration
4
Example
: The configured remote IP address within the VMSE is 129.1.2.3 and the
TCP port number is 1234 :
C121.2.4.5/1<
ENTER
>
complete override - connection is started with host 121.2.4.5, port 1.
C5<
ENTER
>
This means connect to 129.1.2.5, port 1234.
C28.10/12< ENTER >
This means connect to 129.1.28.10, port 12.
Datagram Mode
When selecting this option you will be prompted for Datagram type
Datagram type: 01 (Directed UDP)
Modem Emulation Mode
In modem emulation mode, the VMSE presents a modem interface to the attached
serial device by accepting AT-style modem commands and “wiggles” 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/her PC to the
remote machine and accumulate phone charges for each connection. With the VMSE
in modem mode, you can replace your modems with VMSE and use an Ethernet
connection instead of a phone call all without having to change communications
applications and make potentially-expensive phone calls.
Modem mode is selected by setting the “connect mode” to 0x06 (no echo &
acknowledgments) or 0x16 (with echo & acknowledgments.) In modem mode the
following strings can be used:
ATDTx.x.x.x,pppp or ATDTx.x.x.x/pppp
This is used to make a connection to an IP address (x.x.x.x) and a remote port
number (pppp.)
ATDTx.x.x.x
Without a port number, this will make a connection to the remote port number
defined within the VMSE.
ATD
If no remote IP address and port number are defined within the VMSE, this
command will force the VMSE into “monitor mode”.
