I'll try that tomorrow, the machines are at work.  Does anyone know how the 
getty determines something is there?  Is it just receiving any character?  
Because I had hardware flow turned off, and a breakout box on the serial 
line, and all the control lines, RTS, CD, DTR, etc. seemed to be doing 
nothing.  So it must start the login when it gets a character, or newline, or 
something.  But, it's not that critical.

Anyway, I better get the getty off.  heh-heh ;~)  Does all this mean that 
getty won't work if the console on serial port is not compiled into the 
kernel?
