[aprssig] RE: WRT54G

[Danny Messano]

Partially true.. 

The WRT54GL is the (L)inux version and has a lot more RAM and is even more
customizable than the WRT54Gv4 was.  It will support things like USB and
adding either SD or CF cards (I don't remember which).  These are still
being made and supported.

You do remember correctly. :)

The first serial port is a full fledged serial port (TX/RX plus RTS/CTS and
other control signals).  The second serial port is a kludge of sorts using
the GPIO (general purpose input/output) pins to twiddle the
MAX232 chip.  This second serial port is a two wire port only, it will not
have any form of control signals.  It will also require a specialized driver
to make it work.  The first serial port is supported directly by the kernel
as a true port.

The WRT54G version 4 is the last version that supports OpenWRT.  After that,
Linksys went with a proprietary bootloader and OS that precludes installing
OpenWRT.

But seeing the recommendation for the Asus WL500, I might just have to pick
one up and play with it.  The WRT54G negotiates 100 Mbit connections and has
(in
theory) a 100 Mbit switch but the Broadcomm chip used on board can't push
speeds beyond 10 Mbit full duplex.
 I've been thinking of replacing it with something that can.  Then again,
I've been thinking of replacing it with a full computer that can do layer 7
routing, but that's just me. :)
