+<p>Nokia phone can support three protocols of transmission over cable:\r
+\r
+<p>\r
+<ul>\r
+<li>M2BUS (called often simply MBUS) - 9600,N,...</li>\r
+<li>FBUS - 115200</li>\r
+<li>AT mode - 19600</li>\r
+</ul>\r
+\r
+<p>You cable can support each of them...and phone must be compatible with it\r
+(for example, CAN'T use DLR-3 with phone, which show "headset connected"\r
+after connecting it)...\r

+<p>Simple M2BUS (only) cable:\r
+<p><img src=cable1.gif>\r
+<p>Note:\r
+<br>\r
+<ul>\r
+<li>74HC04 must be in HC version</li>\r
+<li>Dioda Zenera 3,2 V it required for phones different than 21xx, 3110</li>\r
+</ul>\r

+\r
+<p>Switch for M2BUS/FBUS for cable above:\r
+<p><img src=switch.gif>\r
+\r
+<p>Cable for AT mode is unavailable here, because it needs programmed chip\r
+and I don't know, what programm should be inside...\r
+\r
+<p>To make FBUS/MBUS cable you have to connect:\r
+<p>\r
+<ul>\r
+<li>FBUS - GND, TX and RX</li>\r
+<li>M2BUS - MBUS and GND</li>\r
+</ul>\r

+Sell with Nokia Cellularware (it isn't produced now).\r
+</li>\r
+\r
+<li>\r
+DAU-4S - cable for Nokia 3110 and all models in series 8100 (8110, 8110i, 8148 and 8148i).\r
+Sell with Nokia Cellularware (it isn't produced now).\r
+</li>\r
+\r
+<li>\r
+DAU-4F - uniwersal (FBUS/M2BUS) cable without switch,\r
+for Nokia 3110 and all models in series 8100 (8110, 8110i, 8148 and 8148i).\r
+Sell with Nokia Cellular Data Suite 1.0 (it isn't produced now).\r
+</li>\r
+\r
+<li>\r
+DAU-9P - uniwersal (FBUS/M2BUS) cable without switch, for Nokia 51x0/61x0.\r
+Sell with Nokia Cellular Data Suite 1.2 - 3.0a.\r
+</li>\r
+\r
+<li>\r
+DLR-1 - cable sell with Nokia 9000 Communicator. It can be used\r
+to exchange date between phone and computer and installing software into phone.\r
+It's M2BUS cable.\r
+</li>\r
+\r
+<li>\r
+DLR-2 - cable sell with Nokia 9110 Communicator. It can be used\r
+to exchange date between phone and computer and installing software into phone.\r
+It's M2BUS cable, but can't be used with programs working with this protocol (needs\r
+some small changes - after them will not work original Communicator programms).\r
+\r
+<li>\r
+DLR-3 and DLR-3P - cables for Nokia 7110/6210. Supports AT mode and FBUS.\r
+FIXME: MBUS too ?\r
+</li>\r
+</ul>\r

+\r
+<p>See post from gnokii maillist:\r
+\r
+<p>The dlr-3 CAN'T work with the older phones. this is because the \r
+converter in the cable is powered by the phone. this is done by the \r
+phone by raising the !mic-gnd! pin to vcc. if the cable doesn't \r
+repond on the mbus after 1 second, the power is dropped. a older \r
+phone doesn't do this, so the converter is unpowered.\r
+\r
+<p>To decide if a phone needs a dau-9 (the old one, powered by pc) or \r
+the new one (dlr-3) simply connect a dlr-3 to the phone. if the \r
+phone says "headset connected" it isn't capable of using a dlr-3 \r
+and you have to change to a dau-9.\r
