What does the above error message mean exactly? Am I losing > data on the line? > Peter, According to the cy(4): * cy%d: tty-level buffer overflow. Problem in the application. Input has * arrived faster than the given module could process it and some has been * lost. Actually this means that there are problems somewhere in FreeBSD kernel or Cyclades Cyclom-Y driver. This is happening only with PCI Cyclom-Y cards (for me). So, I guess you're using Cyclom YeP version, right? 1. login via serial port 2. run yes(1) (it will print `y' until interrupted) 3. switch to console (/dev/console) You'll see your console is full of ``buffer overflow'' messages. And, YES, you're loosing data. Sometime ago I was using 8YeP card, and I had problems with dial-in ppp due to this `overflows'. After I switched to ISA card (now I use 16Ye rev.1.x) the problems are disappeared.
