[c-nsp] USB to serial converter

[Daniel Hooper]

Or maybe Cisco could just catch up with the rest of the world and do
away with serial ports seeing as it's difficult to get a laptop or PC
with a serial port built in.

Maybe just a local Ethernet port which has a hard coded IP address on it
that cannot be modified? Or an lcd display on your router/switch that
allows configuration of an ip address to manage the device?

The more I think about it the more I can see the hassles in it, no
password resets, no uploading of boot images in case you lose the
running image.. but surely there is something better out there then
serial console port? Anyone got any ideas'?

This is why on another listserv's short list of "tools for techs to
have", a
laptop with a real serial port was near the top of everyone's list.  In
our
workplace that's a requirement for any tech laptop we buy.  We've wasted
way
to much time installing drivers, recovering from blue screens and lock
ups,
and toting along and digging out yet another cable.  

The others have given you suggestions for your current issue, though.

I bought a Prolific USB to serial controller
(http://tinyurl.com/35ocwv [ebay.com]) to get access to my Cisco 2950
switch through my laptop's USB port. I tried from OpenBSD 4.2 on
/dev/ttyU0 and /dev/cuaU0 using cu, tip and minicom with baud rate
9600 and 8,N,1 with no luck. I also tried from Vista with Hypter
Terminal on COM4 but it's not responding. The only thing I get from
OpenBSD with /dev/ttyU0 is a lot of garbage characters at the
beginning (nothing happens after the garbage) -

..5%(.!3..=.((((3'=./A-#-.(((('!=7A/5'.5((((;!!. .-.9/.('5.
..5%((W/5(3!''!.-#1(9!%%=#7.(.-''(-#-.-='-53'=./(3-'5.
..5%(/=.(;55#(-#.5..57(.!.!(-#-.-='-.=..=..9..9.9.O%!75%(3-

The device is detected on OpenBSD as Prolific Technology Inc.
USB-Serial Controller, rev 1.10/3.00.

Could anyone help me with a solution or recommend a new converter for
Cisco 2950 switch?

Any help would be really appreciated. Thanks.
