CN2610 User’s Manual Setting Up Multi-Host TTY

4. Compile and link documents:

SCO OpenServer : # make sco

SCO UnixWare : # make svr5

UnixWare 2.1.x, SVR 4.2 : # make svr42

Configuring tty Redirection

The following example illustrates how to map and redirect a tty device to a MOXA CN2610 serial

port. Use vi or any other text editor to add or modify entries in the file moxattyd.cf. There are

three columns: Device Name, CN2610 IP address, and TCP port number in the entry for the file

moxattyd.cf.

Device Name CN2610 IP address TCP Port number

ttyp1 192.168.1.1 4001

ttyp2 192.168.1.1 4002

ttyp3 192.168.1.1 4003

ttyp4 192.168.1.1 4004

NOTE

1. Device Names for SCO OpenServer are ttyp[n], for SCO UnixWare, SVR4.2 are pts/[n]. The

value of n should be equal or larger than 11 to prevent from conflicting with the device names

of functional keys in some UNIX systems.

2. Default TCP port numbers are from 4001 to 4016 for the 16-port CN2610. If necessary, you

can customize the TCP port numbers. However, the numbers you use MUST be the same as

those defined in MOXA CN2610.

Adding Fixed TTY driver to system booting procedures

To include Fixed TTY driver in the booting system, add the moxattyd daemon process to the

/etc/inittab file. The following example illustrates how to add the full path name for

moxattyd to the entries of /etc/inittab.

ts:2:respawn:/usr/etc/moxattyd/moxattyd –t 1

NOTE

The option “–t 1” means the reconnection time is 1 minute after turning CN2610 on or off.

Fixed TTY Driver for Different Applications

This section illustrates how to use Fixed TTY driver with a number of different applications.

Terminal Access

To use terminal access, the process getty must be activated when the system boots up. To do this,

add the following entries to the file /etc/inittab. For instance,.

ts1:234:respawn:/etc/getty ttyp1

ts2:234:respawn:/etc/getty ttyp2

ts3:234:respawn:/etc/getty ttyp3

ts4:234:respawn:/etc/getty ttyp4

NOTE

ttyp1 to ttyp4 device names are mapped to port 1 to port 4 on MOXA CN2610.
