Hello Yuriy,

Thanks for reporting this issue. We should fix this.

Could you give me the output of `pstat -t' while using `ppp'? What
device node/device driver are you using? I know there are some things
fishy w.r.t. flow control, so there are a lot of things we can look in
to.

Is it somehow possible to get some kind of `debug output' from the
Windows machine as well? Thanks!
