Kill them manually from a console. I can watch them with "top" . Using the
exact same scripts on the same Operating system (DSL) on a Athlon 1800
desktop and a mobile Pentium M 1600 laptop these scripts run and terminate
fine..
Whats wrong here ? Below is a sample of a script.. Each machine uses the
same OS same Kernel and same scripts .. The odd thing out seems to be the
Celeron 366 laptop .
I am using Damm Small Linux v 3.4.1 live from a USB stick which is 2.4.26
Debian Kernel .
#!/bin/sh
# KissOn for Com1 TNC2 MFJ etc
stty 9600 cs8 -parenb -crtscts -F /dev/ttyS0
sleep 2
echo -e "\r kiss on\r restart\r" >/dev/ttyS0
sleep 2
exit 0
I'm no expert here, but I would look closely at '-crtscts', which is
asking for hardware handshaking. Laptop serial ports are sometimes only
partially implemented, shall we say? Does it support the handshake? Does
your cable include the handshake lines?
The script may be fine. It may simply be waiting for permission to send
the first byte.
