Hello everyone. I'm having some trouble with com 3 on a 7260 board.
I've got the driver kernel modules loaded, and am able to start a
getty process on the port via:
getty -L ttyTS0 57600 vt100
With that, as expected, the login prompt is presented on the terminal
that's attached (minicom on my laptop over a seral->usb cable attached
to the pigtail that came from TS). The trouble is that when I try to
log in nothing I type into the terminal appears to be making it to
through the port. If I attach the serial cable to com 0 on the ts7260
and fire up a getty process on ttyAM0 with the same settings, I'm able
to log in without trouble. The settings on the port (as reported by
stty) are:
root# stty -F /dev/ttyTS0
speed 57600 baud; line = 0;
min = 1; time = 0;
-brkint -icrnl -imaxbel
-opost -onlcr
-isig -icanon -iexten -echo -echoe -echok -echoctl -echoke
These settings are identical to what's set on ttyAM0.
I've tried lots of different combinations of flow control settings,
different baud rates, etc, and I just can't get beyond this issue. At
this point I'm convinced I'm either overlooking something so simple it
hasn't occurred, or there's something wrong with the port.
Any ideas on what to try next? I'm at a bit of a loss.
Thanks!
Steve
