Configuring Eiconcard Host PAD Devices
Once the Eiconcard Host PAD driver has been installed and configured, it may be necessary
to change the setup of the various Eiconcard Host PAD tty devices. In most cases, the default
setup for the Eiconcard Host PAD devices should suffice. The following steps describe how to
change the default terminal type and parity settings:
1. Login as root.
2. When Eiconcard Host PAD was installed, a line was added to /etc/inittab for each device.
The /etc/inittab file contains these lines:
Et00:2345:off:/sbin/getty ttyEt00 hpad_8n
Et01:2345:off:/sbin/getty ttyEt01 hpad_8n
Et02:2345:off:/sbin/getty ttyEt02 hpad_8n
Et03:2345:off:/sbin/getty ttyEt03 hpad_8n
Et04:2345:off:/sbin/getty ttyEt04 hpad_8n
Et05:2345:off:/sbin/getty ttyEt05 hpad_8n
Et06:2345:off:/sbin/getty ttyEt06 hpad_8n
Et07:2345:off:/sbin/getty ttyEt07 hpad_8n
This example assumes that you are installing the eight default Host PAD devices.
The Eiconcard Host PAD devices need to be enabled before you can use them. Set the
action field from ‘off’ to ‘respawn’ or similar. See the inittab man page.
3. If you need more than one Eiconcard Host PAD device configuration, add entries to the
/etc/gettydefs file. When the Eiconcard Host PAD was installed, a default setup for its
device was added to the /etc/gettydefs file with the following line:
hpad_8n# B9600 SANE HUPCL # B9600 CS8 SANE HUBCL TAB3 ECHOE IXANY \
#login: #hpad_8n
This line defines communications features such as baud rate and parity settings for the
Eiconcard Host PAD. This default gettydefs or ttydefs definition sets the Eiconcard Host
PAD to “8-bit none, no strip of parity,” which satisfies the needs of most installations.
However, you may want to construct your own gettydefs definitions and assign them to
unused codes. For details and instructions, see your Linux system administrator’s
documentation or the gettydefs man page.
4. To complete the Eiconcard Host PAD device configuration, verify that settings in the mgetty
configuration file (/etc/mgetty+sendfax/megetty.config/megetty.config) match the
configuration of your system. The config file is grouped into port-specific sections,
separated by port <tty-name> lines. Everything before the first port line specifies global
defaults; everything between two port statements specifies configuration items valid only
for this device.
