setinterface device-node [interface-no]

device-node: /dev/ttyMn; n = 0,1,2,...

interface-no: [see following table]:

interface-no Operation Mode

None Display current setting

0 RS-232

1 2-wire RS-485

2 RS-422

3 4-wire RS-485

For example, use the following commands to set /dev/ttyM0 to RS-422:

MOXA:~# setinterface /dev/ttyM0 2

MOXA:~# setinterface /dev/ttyM0

Now setting is RS422 interface.

MOXA:~#

NOTE

The V2422 and V2426 can be used with two expansion modules with eight serial ports. The corresponding

device nodes would be from ttyM8 to ttyM15.

Telnet/FTP Server

In addition to supporting Telnet client/server and FTP client/server, the V2406/2422/2426-LX also supports

SSH and sftp client/server. To enable or disable the Telnet/ftp server, you need to edit the file

/etc/inetd.conf.

1. Mount the root file system with write permission.

MOXA:~# mount -o remount,rw /dev/hda1 /

2. Type # cd /etc to change the directory.

MOXA:~# cd /etc

3. Type # vi inetd.conf to edit the configuration file.

MOXA:/etc# vi inetd.conf

Enabling the Telnet/FTP Server

The following example shows the default content of the file /etc/inetd.conf. The default is to “enable the

Telnet/ftp server:”

discard dgram udp wait root /bin/discard

discard stream tcp nowait root /bin/discard

telnet stream tcp nowait root /bin/telnetd

ftp stream tcp nowait root /bin/ftpd -l
