Comment 10 for bug 482623

I have a similar problem. Don't know how much it's related and if it should be a separate bug report.

Server: Lucid with byobu 2.75. Client: MacBook Pro running Snow Leopard 10.6.3.
Empty .screenrc.

When I ssh into the server and run just run screen then dumptermcap dumps the lines

        :po=\E[5i:pf=\E[4i:k0=\E[10~:k1=\EOP:k2=\EOQ:k3=\EOR:\
        :k4=\EOS:k5=\E[15~:k6=\E[17~:k7=\E[18~:k8=\E[19~:\
        :k9=\E[20~:k;=\E[21~:F1=\E[23~:F2=\E[24~:F3=\EO2P:\

When I run byobu instead it dumps

        :k0=\E[10~:k1=\EOP:k;=\E[21~:F1=\E[23~:F3=\E[25~:\
        :F4=\E[26~:F5=\E[28~:F6=\E[29~:F7=\E[31~:F8=\E[32~:\

Which lacks all the k2, k3, ..., k9 capabilities as is to be expected.

However, F2, F3, and F4 don't work, i.e., they only cause the terminal to beep.
Even if I manually enter, say, "^a:bindkey -k k2 screen" the result is the same.
If I enter the same in the first-mentioned screen session I succeed.

Anything ideas?
