Title: "Sh Conf" Problem in SW/20-TCP Ver. 3.2
date: 6/22/90

When the "sh conf" command is executed using SW/20-TCP Version 3.2,
extra blank lines appear in the output.  This problem occurs only on
disk-based systems when the command is executed from either a local
terminal or a remote station.

The problem is due to the disk the software is on, and has been confirmed
on the master diskette.  The first configuration directory sector (429) is
filled with bytes of "FF" rather than "00"; this makes it look like there
are numerous configuration files named "0xFFFFFFFFFFFFFFFFFFFFFFFFFFFF."
The false files do not actually print, but they display blank lines.
When the "sh conf" command is executed from a remote station, the problem
is more severe due to the data compression used.

Sites that are upgrading from 3.0 usually do not see the problem
because they copy over their old configuration files and directory.

Sites that are using fresh disks can fix the problem by using the
following monitor commands to modify that disk sector:

1.  Reset the CS/1.

2.  Make a copy of your working diskette.

3.  Reset the CS/1 again.

4.  Check to see if the first configuration directory sector is really
all F's by typing the commands after the ">":

    > r 429 4001000 200
    > dm 4001000 200

5.  If only FF sequences appear, then type the following commands:

    > fb 4001000 200 0
    > cw 4001002
    4001002: 0000 ? 3030   (Type 3030 after the ?)
    4001004: 0000 ?        (Type . after the ?)
    > w 429 4001000 200

This puts zeros in the first configuration directory sector.  At least
one nonzero byte at 4001002 is needed to show that the directory is
not empty.
