Enabling Callout Functionality
To enable the callout() functionality, perform the following steps:
Step 1. Create the following device files:
•
/dev/ttydXYZ
• /dev/culXYZ
• /dev/cuaXYZ
Step 2. Add getty entry to inittab as follows:
ID:3:off:/usr/sbin/getty -h ttydXYZ baud
NOTE ID should be a unique value, like a1, a2, a3 and so on. Select a value
which is not present in the /etc/inittab.
For Example:
To create the device file /dev/ttyd3a3, enter the following command at the
HP-UX prompt:
# mksf -v -d pci_mux0 -a2 -pa4
To create the device file /dev/cul3a4, enter the following command at the
HP-UX prompt:
# mksf -v -d pci_mux0 -a1 -pa4
To create the device file /dev/cua3a4, enter the following command at the
HP-UX prompt:
# mksf -v -d pci_mux0 -a0 -i -pa4
Add the following getty entry to inittab:
a1:3:off:/usr/sbin/getty -h ttyd3a4 9600
