Well.... Bad news.
I confirmed that the serial port on the Linux box can talk to the USB-serial
cable on the laptop at 115 kbps -- minicom on Linux, HyperTerm on Windows. Good
data in both directions, one key at a time from the other end.
HOWEVER, neither 7250 will log me in on the serial port. I see the standard
boot-up messages, but there is NO response when I type 'root' at the login
prompt. On the 'operator' 7250 (network name, static IP), I can log into
Telnet, and the serial console displays additional messages. I can 'shutdown -h
now' on the Telnet console, and the serial console displays the shutdown
messages. The serial port is configured 8N1, 115200bps.
Here is a link to the full minicom session
<http://mdodd.com/files/minicom_7250.txt> and here is a link to the Telnet
session <http://mdodd.com/files/telnet_7250.txt>.
The tail-end of the minicom session, showing the serial login attempt and
messages resulting from Telnet activity looks like this:
----------------
Starting telnetd...
Starting apache.../www/apache/bin/apachectl start: httpd started
Technologic Systems TS-LINUX/arm 7.0
operator login: root [NO RESPONSE ON SERIAL PORT]
THIS SHOWED UP WHEN I LOGGED INTO THE 7250 USING TELNET---> login[81]: root
login on `pts/0'
ls -l [NO RESPONSE ON SERIAL PORT]
THIS SHOWED UP WHEN I ISSUED 'SHUTDOWN -H NOW' ON TELNET ---> login[82]: root
login on `pts/0'
INIT: Switching to runlevel: 0
INIT: Sending proó
The system is going down NOW !!
Sending SIGTERM to all processes.
INIT: no more processes left in this runlevel
Sending SIGKILL to all processes.
System halted.
----------------
I'm stumped. Why won't either 7250 log me in on the serial port?
