I have problems using USB to RS232 converter under FreeBSD 6.3-STABLE when connecting to any Cisco gear over serial link. I connect my adapter to notebook and dmesg output looks like this one: ucom0: Prolific Technology Inc. USB-Serial Controller D, rev 1.10/4.00, addr 2 I have also following modules loaded: 8 1 0xc0c17000 3540 umodem.ko# cu -l /dev/ttyU0 Connected 9 4 0xc0c1b000 3208 ucom.ko 10 1 0xc0c1f000 2f54 uplcom.ko 13 1 0xc0c2f000 3384 ubsa.ko Now I try to connect to Cisco box: # cu -l /dev/ttyU0 Connected And terminal stalls- nothing happens- it ignores keyboard completely- sometimes it works but then suddenly lost keyboard interactivity. I tried from KDE Konsole, from plain tcsh command line, sometimes I am able to gain Cisco command line but 90% of times it just hangs. I got two usb2serial adapters: Trendnet TU-S9 and Manhattan 205146. Same converters works just fine under Windows and Linux (drivers cd even got RedHat 7, 8 and 9 versions source code drivers- http://www.manhattan-products.com/driver-usb-rs232.shtml).
