Hello.
Would you, please, comment the kernel message below:
sio0: 478 more tty-level buffer overflows (total 478)
I use FreeBSD 2.2.8; there is a modem (without hardware flow control)
on /dev/cua0; I have a leased line with 38400 bps full duplex;
there is PPP (user mode) tunnel to my ISP.
Can you answer what are these buffers (kernel or UART 16550A) and
how can I fight with these buffer overflows.
Thank you.
