16 port adapter unable to run tty's at 9600 baud rate

16 port adapter
After upgrade from 3.2.3 to 3.2.5 some of her terminals
were experiencing getting extra characters on the RAN and 16-port
adapter. She said that when she upgraded from 3.2.3 to 3.2.5, it
did not install the /usr/lib/terminfo directory. When she installed
this over the weekend, this fixed the problem on the RAN's but the
16-port adapter was still not working. I told her to remove and re-add
the 16-port adapter.
ACT: The ttys (on the 16 port adapter)
do not have the correct terminfo.
there is no link between the:
/usr/lib/terminfo --> /usr/share/lib/terminfo
we set up the link by:
1) cd to /usr/lib
2) ln -s /usr/share/lib/terminfo terminfo
Now the tty is working fine.
The tty hanging off the native port and 128
adapter work fine in SMIT (the box drawing character). The ttys
hanging off the 16 port adapter do not work in SMIT (no box
Found similiar problems that were data refresh problems
with tty's after an upgrade to 3.2.5 enh 4. 3668x reports that the
problem also occured on printers attached to the 16-port adapter. I
would like to know if the same results are seen on native serial port.
Check baud rate and find out if problem occurs at 9600, but not
other rates. If so apply 172752.
Verified that changing the baud rate to 19200 eliminates the
problem. PTF to fix this problem is U438539.
