(Please gurus, no flames...corrections welcomed.:-) After entering kermit and setting the line to your cua0? dialout, run stty -f /dev/cua0? speed 38400. Then try changing your speed in kermit. (Careful with your terminology: bps != Baud; and it should be capitalized.) I just changed /sys/sys/ttydefaults.h to default to 38400 bps using CRTSCTS and no software flow control. >2) Why were the serial line device files in FreeBSD 1.02 tty files, and now >they are cua device files in FreeBSD 1.1.5.1? As I understand it, cua are for dialOUT on a modem (also called dial"up"), ttyd are for dialIN on a modem, and tty0 are for hardwired terminals (i.e. EIA-232 serial ports without a modem). Then there are also the pseudo tty devices so that software using the network can have a controlling device file. If you have a modem on ttyd0 (using sio0) with a getty running on it, you can still dialOUT using that same modem using cua00, because the getty for dialIN on ttyd0 is put to sleep until the dialOUT is no longer being used. What are the different cua* names for??? I don't understand that (yet).
