I believe I have discovered a bug in something that effects transfers of data over a serial line (not on a modem). The problem is that the above kernels somehow break kermit, xmodem, zmodem etc., transfers over a direct connection. I discovered this when I tried to use kermit to talk to my HP 48Gx calculator and my Palm Pilot IIIx. Both of these devices can be communicated with using the same cables on my Solaris box.
Umm.... how does it break? You haven't given me any information about your setup. What RS-232 lines are involved? Are the modem control lines connect? What about CTS/RTS? What are your termios settings? If the modem control lines aren't connected, better make sure CLOCAL is set. If CTS/RTS aren't connect, better make sure CRTSCTS are clear. I can't really debug this with the small amount of information you've given me.....
Here is a post that illustrates the problem and a possible cause for such;
Errr... the post you sent was about what appears to be an unrelated bug report involving a radio modem. Why are you convinced it is the same problem? From their description, they don't sound related at all.
Where did you find that post, and do you have the e-mail addresses of the people who sent that post. They seem to be very confused, and I'd like to help them out, but I'll need their e-mail address. For example, it's not clear why the enabled CRTSCTS if they said that "flow control must be disabled".
