input overrun error

Hi

I am using a small local ISP and having a problem with being disconnected during sessions.

I spoke to my system administrator and he says that while a number of other clients have reported the same problem, he has no clue as to why it is happening.

He says the only possible clue is a Linux error message which has popped up on the server reasonably frequently which says "input overrun on tty6".

He has no idea what the message means and has been told by his "technical expert" that it means nothing!

He says from his point of view there is no other indication that anything has gone wrong while I am connected.  All that his log shows is that I have disconnected and then I have connected again a short time later.

From my end, I have NOT noticed this happening at all while running my mail program (Eudora Pro), but it happens almost every time I use Netscape for any length of time (more than an hour).

It also seems that it happens more when there is a large amount of data moving (or it is running very fast) and frustratingly it seems to occur lots when I am trying to download a program from the net!

Also, once it has happened it seems to occur more frequently.  For example, it has not yet happened today, but if it does, it will most likely occur three or four times (until I give up in frustration for the day!)

There is no error message at my end when it happens, the modem lights just go out and the data stops transferring.

If you can give me a line on whether the Linux error message at the ISP has something to do with my problem I would be grateful.

Thanks

I guess you or your ISP (or both of you) use XON/XOFF (software) handshake.
You should be using RTS/CTS (hardware) handshake.
My guess is that your ISP is using XON/XOFF.
If your ISP uses Gert Doering's mgetty it might be compiled with the XON/XOFF (software) flow control.

Thanks,  I don't have software handshake switched on, but will check with my ISP to see if this solves the problem.
