[ECOS] odd serial input bug in redboot 095308 20010607 on iPaq

[David Bliss <david at ytterby dot dbsi dot org>]

I've just installed RedBoot 09:53:08 Jun 7 2001 on my iPaq HPC.  I'm having
some trouble. 

When it's cold-started (battery switch turned on), it will
output its banner to the serial console:

+FLASH: 0x50000000 - 0x51000000, 64 blocks of 0x00040000 bytes each.
... Waiting for network card: ..........No network interfaces found

RedBoot(tm) bootstrap and debug environment - built 09:53:08, Jun  7 2001

Platform: Compaq iPAQ Pocket PC (StrongARM 1110)
Copyright (C) 2000, 2001, Red Hat, Inc.

RAM: 0x00000000-0x01fc0000, 0x0001ff00-0x01f70000 available
RedBoot>

But it will not accept any input from the serial console, only from the
keyboard.

If I boot into Parrot (where the serial interface works flawlessly) and then
boot RedBoot, it works.  If I warmboot after that (reset command) it works.
But every time I cold boot, no serial input.

Since running Parrot makes it work, I'm guessing that perhaps the UART 
initialization leaves something to be desired?

Anyway, it's a pain, though not a showstopper, but someone more knowledgeable
than I might want to take a look at it.

I'm more than happy to offer remote login to the machine if anyone wants
to look at its configuration.
