Description of problem:
using minicom in a terminal window, connected via usb-serial adapter
connection to another linux machine also using minicom, but internal
serial connector, I can freese the entire laptop ( Compac evo N800v )
simply by sending a lot of data to the laptop ( ctl-z-s, ascii )
and while the data is flowing into the laptop terminal window, I issue
a quit of the minicom ( ctl-z-x ), and it freeses in ( leave minicom - yes no ).
If I try the same in run level 5, not in graphical mode this does not
I have tried this while connected to the laptop over the network
and the network freeses also
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.On the laptop, having no serial connection, connect usb-serial adapter
2.connect serial1 from another linux to the serial port on the usb-serial, use
null modem cable
3.issue minicom , using /dev/ttyS0 on the linux ( rh 8.0 )
4. issue minicom, using /dev/ttyUSB0 on the laptop ( linux rh 9.0 )
5. send a large ascii file from the linux ( ctl-z-s , ascii mode ) to the
laptop, and while the laptop is receiving the file into the terminal window,
issue ( ctl-z-x ), and the laptop freeses...
Actual Results: laptop freeses ( I believe the reason is buffer overflow )...
Expected Results: in non graphic mode, the minicom just exits
The usb-serial product is BAFO BF-810
The usb-serial converter is from BAFO, model BF-810
*** Bug 90910 has been marked as a duplicate of this bug. ***
I don't have the equipment. Is there a way to create the same
effect in text mode outside of KDE? For instance, I use kermit
for serial communications. The reason for doing it is to try
and catch any failure messages.
I have not been able to get this effect ( lockup ) in text mode
only in KDE..
I've also seen this happen. I think it's the USB->Serial driver thats acting up.
There is quite a lot of discussion about this on the GPSDrive mailinglist.

I think this is a dup of bug 90442, most likely.
