I'm trying to use minicom on Fedora Core 4 to speak to a PIC18F452 chip
which contains a preloaded version of the Microchip TCP/IP stack. I
built the device myself from a kit; it is intended to be a small web
server. My objective is to assign an IP address to the RTL9019AS
ethernet controller. This can be accomplished over a setup menu that
appears in the minicom window. I suspect I have incorrect minicom settings.
Serial device -- /dev/TTYS0 connected to development board Max232 chip
setup for 19200 bps,8N1, software flow control, VT102 emulation
iptables service is stopped
When I connect, the setup program appears. It is just a menu with 8
choices. In fact, the setup menu sometimes displays itself twice.
I select an option say 2 to set the IP address. The device very
sensibily responds with the default ip address. I type in a new IP
address to reflect my actual network.
If I try to select 2 to check the default IP address, it again sensibly
responds with the new IP address that I just gave it. So far, so good.
Then I select the option to save the new IP address. a message is
returned which is usually the new IP address itself.
Attempts to ping that IP address fail.
Then I start the setup menu again in a new minicom window. The original
-- default -- IP address appears.
So it seems like the option to save the IP address isn't working right.
Things are apparently lost when I restart the device.
Is this a minicom software issue, or is it bad soldering on my part with
the actual device being tested? I'm quite willing to agree it may have
soldering issues.
Thanks
