  1. When rebuilding the kernel in ATT Unix SVR4 I get a message ERROR: unknown tunable parameter '-g'
  2. How do I enable a terminal in SVR4 or SVR5?
  3. Terminal initially receives login and works fine until the terminal is powered off and turned back on, then either the login won't appear or garbage characters will display on the screen. User has to reboot or disable/re-enable.
  4. How do I get ports to display in scoadmin Serial Manager for UnixWare 7.0.1?
  5. How can I map TERM type to port name under UnixWare 7.0.x?
  6. How can I get ttymon to run on my modem ports under UnixWare 7.x?
  7. Why am I having trouble dialing into my UnixWare 7.1.x system?

When rebuilding the kernel in ATT Unix SVR4 I get a message ERROR: unknown tunable parameter '-g'

edit the /etc/conf/cf.d/stune file to remove the last line which has a -g flag on it The rebuild should now work correctly.
How do I enable a terminal in SVR4 or SVR5?

Command to enable a terminal in SVR4 or SVR5
pmadm -a -p ttymonx -s a01s -fu -i root -v `ttyadm -V` 
     -m "`ttyadm -d /dev/term/a01s -l 9600 -s /usr/bin/login`"
    where:
  • ttymonx - is the port monitor tag such as zsmon.
  • a01s - is the name of the port. Refer to your Digi manual for your device names.
  • -l 9600 - sets the port for a baud rate of 9600.
The above command will enable the port for 9600 8,1,N. Consult your documentation if you wish to change these parameters.
Terminal initially receives login and works fine until the terminal is powered off and turned back on, then either the login won't appear or garbage characters will display on the screen. User has to reboot or disable/re-enable

In SVR4 when the terminal is turned off/on the port gets auto-bauded. To fix edit the /etc/ttydefs file, go to the entry refered to by the ports ttylabel. To know the ttylabel of a port run

sysadm --> ports --> port services --> modify
change the last parameter so that it is the same as the initial ttylabel entry.

Example: In sysadm the port's ttylabel entry is 19200NP, in the ttydefs file the entry will look like;

19200NP: 19200 opost onlcr tab3 cread hupcl -parenb ::9600NP
Change the final entry ::9600NP to ::19200NP

How do I get ports to display in scoadmin Serial Manager for UnixWare 7.0.1?

UnixWare 7.0.1 will require a patch (as of 6/10/99) which can be obtained from SCO's ftp site:

  • ptf7053b.Z ftp://ftp.sco.com/SLS/ptf7053b.Z
  • ptf7053b.txt ftp://ftp.sco.com/SLS/ptf7053b.txt
  • How can I map TERM type to port name under UnixWare 7.0.x?

    SCO provides technical articles on their web site for configuring term types, below are the URL's:

  • 109949.
  • 109948.
  • How can I get ttymon to run on my modem ports under UnixWare 7.x?

    SCO UnixWare's Serial Manager places a 'P' flag in the /etc/saf/ttymon#/_pmtab file. Remove this reference and restart the ttymon. Or download the port_config shell script.
  • port_config

  • Why am I having trouble dialing into my UnixWare 7.1.x system?

    As of 8/30/99 we found that the following SCO UnixWare 7.1.0 patches were needed for modem functionality:

  • ptf7401c
  • ptf7423a
  • ptf7424a
