Hi Sun Managers:

I wish to thank the following persons for responding to my question:
Stefan Voss
Kevin Sheehan
Rich Fincher
Bismark Espinoza

Stefan was kind enough to point out that my syntax was not correct, and
gave me this command to run: # ps -elf | grep "term/b" | grep -v grep | awk
' { print $4 } ' | xargs -i -t
kill -9

This did return me to the # prompt without any error messages, but when I tried
to do tip/dev/cua/b, I still received the all ports busy message.

Kevin suggested I run this command: echo '$<threadlist' | adb -k
and look for a thread using the zs driver , and figure out which one is using
ttyb.

I ran the command, but as I am not a programmer, I really couldn't
distinguish any information from what the command returned. I did not see
any zs, or ttyb thread,s but most of the stuff returned was in hexadecimal.
I will try to work through this again when I get time.

Kevin also suggested we update to Solaris 2.6, but that is not an option
for us at this time, unfortunately.

Rich gave me a few suggestions, including checking the eeprom, checking the
modem cable, and checking the modem settings, and he suggested I visit
http://www.stokely.com, which is where I obtained information when I originally
set this up.

Bismark said to check the permissions on dev/cua/b, and when I checked them
they were all lrwxrwxrwx, so I assume that should not be the problem.

I will probably reboot the server Friday afternoon, after work, and then go
back over some of the suggestions, but for now, I'm still not able to kill
whatever process is attaching to ttyb.

Thank you much for the help and suggestions.
