Solution / Recommendation________________________________________________________________________
The embedded system (IP 192.168.51.106) is connected via serial port #2 with the serial port #1 on a QNX hosted PC (192.168.51.90).
This must be added in the IFS on the embedded system (PPC 8313). syslogd, /etc/syslog.conf and touch are just for debugging purposes.
touch /tmp/syslog
slogger
syslogd
io-net -ptcpip
waitfor /dev/socket 4
pppd 192.168.51.106:192.168.51.90 /dev/ser2
[snip]
[type=link] /var/run = /dev/shmem
[gid=0 uid=0 perms=777 data=copy code=uip] /bin/pppd = pppd
[gid=0 uid=0 perms=777 data=copy code=uip] /lib/dll/
npm-pppmgr.so =
npm-pppmgr.so[gid=0 uid=0 perms=777 data=copy code=uip] /bin/ping = ping
[gid=0 uid=0 perms=777 data=copy code=uip] /bin/telnet = telnet
[gid=0 uid=0 perms=777 data=copy code=uip] /bin/ftp = ftp
[gid=0 uid=0 perms=777 data=copy code=uip] /bin/syslogd = syslogd
[gid=0 uid=0 perms=777 data=copy code=uip] /bin/touch = touch
[gid=0 uid=0 perms=777 data=copy code=uip] /bin/cat = cat
/etc/ppp/options = {
-crtscts
debug
/dev/ser2
115200
}
/etc/syslog.conf = {
# The file must exist for logging to occur!!
mail.* /var/log/maillog
*.* /tmp/syslog
}
On the PC run
#! /bin/sh
slay -f io-net dhcp.client inetd fs-cifs qconn
sleep 1
io-net -ptcpip &
pppd 192.168.51.90:192.168.51.106 /dev/ser1
and create the file /etc/ppp/options with the content:
-crtscts
debug
/dev/ser1
115200
You should now be able to ping, telnet and ftp the PC from the embedded system.
