Tried 2400,4800,9600,19200 on the dump terminal. Using AT command to dial in. 2) From a 1.1.5.1 box connected to a Dynalink 14.4K modem and dial-in to the above FreeBSD box. Using kermit to dial in. In both case upon connection I get either : a) No login prompt, absolutely nothing. After a few minutes wait and many key presses, I start getting garbage characters. b) Get garbage characters straight away, and upon key press, more garbage characters. I tried the suggestions above by AT&B1, but that doesn't help either, 8-(( The only thing that seens to work for 1) from a dumb terminal is that I kill the getty job running at the dial-in port /dev/ttyd1 (COM2), and have it respawned, and I get a nice login prompt in a few seconds! Any more advices or suggestions ? Thanksin advance.
