SCO Unix Serial Communications and UUCP

This article is from a FAQ concerning SCO operating systems. While some of the information may be applicable to any OS, or any Unix or Linux OS, it may be specific to SCO Xenix, Open Desktop or Openserver.

This is an old article about SCO Unix and is only left here for historical purposes.

There is lots of Linux, Mac OS X and general Unix info elsewhere on this site: Search this site is the best way to find anything.

How do I change uucico's packet timeout on SCO Unix?

For OpenServer Release 5, see the man page for Configuration. For earlier versions, read on.

This is very similar to changing the window size; once again, you will need to have a copy of adb, and you must first make a backup copy of uucico. Then run the following Bourne shell command:

adb -w /usr/lib/uucp/uucico - << EOF
_pktime/w 5

Replace 5 with the desired number of seconds. Note that you should set this parameter to the smallest value that works reliably. If you specify too large a value, it will reduce throughput if you encounter a bad line or other conditions that require packets to be resent. If you are running Unix 3.2v4, leave the underscore out of the symbol. Once again, restore the permissions and ownership once you're done.
