There are 2 patches related to tty's which i was reffered to: T100513-04 and 100359-06
First one obsoletes all 100513-XX and according to the bugID 1069768, 1064320
will help me to get rid of the headache.
The second ... well nothing like that happend to me so far (thank's god)
Now, the followup question: do these bugs affect *ONLY* built in serial ports ?

Topic: Jumbo tty patch
BugId's fixed with this patch: 1048128 1069768 1008324 1040722 1070495 1060689
1064320 1104557 1068641 1056787, 1068641, 1056787
Patches which may conflict with this patch: 100225-02, 100194-02, 100397-01, 100188-02,
100358-01 and 100414-01. All obsoleted patches.
BugID 1012954:
SunOS does not do RTS/CTS flow control for incoming datastreams, previously
Xon/Xoff flow control had to be used.
BugID 1048128:
When sending output to printers, terminals, plotters etc. using
the ALM2 or zs serial ports with the xon/xoff flow control, the
output may hang intermittently.
Flow control problems exist in SunOS 4.x. After some
extended period of time, the device would send an xoff, and data
would stop. When data is to be resumed with an xon from the device,
the xon seems to have been dropped or ignored because data flow did
not continue.
BugID 1069768:
Sun doesn't respond on xoff at the end of a printjob
BugID 1008324
TIOCCONS can be used to re-direct console output/input away from "console"
BugID 1070495
Kernel programs using pty can get output from previous application
BugID 1040722
Process not letting go of a pty
BugID 1060689
When a port is used for dialing in and dialing out, DTR would be dropped
and processes remain in <exiting> state with data queued for the driver.
BugID 1064320
A remote dialin session using hayes modem drops NULLs
BugID 1104557
In rare circumstances, attempting a TIOCSTI ioctl on a pty, when the
read side of the stream is full, can panic Bad Trap from ttycommon_qfull,
after passing that routine a faulty pointer to the queue.
BugID 1068641, 1056787
SunOS doesn't handle ~HUPCL correctly. Typically this is seen
when one dials in to a Sun zs port, and starts a process which
is supposed to remain attached to the modem after you log off
(E.g. a dialback program). When you log off, SunOS 4.1.3 will
drop DTR. This causes the remaining process to detach from
the modem. Note well that this *won't* be integrated into
future releases.
Patch-ID# 100359-06
