Version 3.5 (sysV) requires 'carrier detect' to be active before the port will open. There is no way to ignore carrier like you can with 4.x bsd. I discoved this the hard way on my 7300 and later verified it with the people at AT&T. It is easy to 'fool' the port into thinking there is a carrier by jumpering pins 6 & 8 on the rs232 connector. -- William M.
