Yes, the GENERIC kernel.

I cannot get anything working with chat, does not see to be communicating with
modem at all, the rd and sd lights don't flicker. the cable does have 8 wires,
i can't turn on the modem RTS CTS without communicating with it, is there some
program i can get that will just redirect input to the modem? (like a dumb
termial program?)

I have tried compliing my own kernel, but it stops and ends up in the kernel
debugger (ddb) with this message:

   ...kern/sys_process.c 
   panic: vm_object_paging_begin
   stopped at: 0f2a0c: unlk a6

I fear this is caused by my crapped Microbotics 8UP card, I am looking into
the SIMMFONIE at this time, do you suggest I get the new card and try again?
or is there something else going wrong? Also to mention because netbsd only
recondizes the 4meg on the motherboard my swap partion is much bigger (24MB).

I have a 14400 modem so there should not be a problem, also to mention that
the null serial line between the PC and Amiga worked great at 115200 (except
when using sz, it liked to stay down to about 38400)
