	* The serial modification is just a MAX3232 (3.3Volt) and five 0.1 ÂµF tantal capacitor (if you need serial speed >115k2 DD4RD suggests to use a MAX3380 which can be obtained at http://www.segor.de for example).		* The serial modification is just a MAX3232 (3.3Volt) and five 0.1 ÂµF tantal capacitor (if you need serial speed >115k2 DD4RD suggests to use a MAX3380 which can be obtained at http://www.segor.de for example).
	* On my WRT54GS /dev/tts/0's default IRQ is 3. /dev/tts/1 is set to IRQ 0. To set /dev/tts/1 to IRQ 3 use setserial. Add "src florian http://openwrt.alphacore.net" to ipkg.conf and install setserial with "ipkg update", "ipkg install setserial". Run Setserial: "/bin/setserial /dev/tts/1 irq 3". Now you can use /dev/tts/0 AND /dev/tts/1 for any serial device at the same time.		* On my WRT54GS /dev/tts/0's default IRQ is 3. /dev/tts/1 is set to IRQ 0. To set /dev/tts/1 to IRQ 3 use setserial.

	* To initialize a Kenwood TH-D7 for KISS-Usage I have a ugly workaround. First Start Digi_Ned with "digi_ned -p /dev/tts/0:9600:1". After startup cancel operation with CTRL+C. The serial ports keeps initialized with 9k6. Now send the TNC-commands for switching to KISS: echo -e "\015softdcd on\015kiss on\015restart" >/dev/tts/0. The TH-D7 will indicate changing to KISS by blinking STA CON on the display.		* To initialize a Kenwood TH-D7 for [[KISS]]-Usage I have a ugly workaround.

Information about the Linksys WRT54G(S) for hamradio usage.

The Linksys WRT54GS WLAN-Router is a powerful cheap device useable for hamradio. It is about 75,- â‚¬, but you have to care which subversion you buy. Please check http://openwrt.org and http://www.seattlewireless.net/index.cgi/LinksysWRT54GS for further details about flash memory and capabilities to use OpenWRT.

Arsene, LX1TB has modified the Linksys WRT54G(S) models to tune the frequencies below 2400 MHz for better fit with the hamradio bandplans ;-)))) Look on his german website to get the details: http://www.rlx.lu/~lx1tb/wrt54gs/.

* You can adjust TX-Power with "wl txpwr 0-255" up to about 160mW. "wl txpwr 100" and above will cause some by-products. Be careful not to overheat the device. Here's a little table (round about):
