thanks Juergen what i've got from your words is: for connecting modem to cisco we should reverse send and receive while for connecting cisco to PC it should be straight. is it true or i misunderstand what you mean?
this connection is so important for me therefore i want to buy a cable but don't know what exactly cable i should buy. please help me to buy a correct one. thanks for your attention On Sat, Nov 17, 2012 at 6:04 PM, Juergen Marenda <[email protected]> wrote: > On Sat, Nov 17, 2012 at 02:22:58PM +0330, s m wrote: > > hello guys > > > > i wanna connect a modem to a 2800 router by AUX port. this is my > > configuration: > > modem InOut > > modem autoconfigure discovery > > transport input all > > stopbits 1 > > speed 38400 > > flowcontrol hardware > > > > the speed value changes because "mode autoconfigure discovery" is set. > > > > i used blue console cable RJ45 to DB9 for connecting AUX port to modem. > > use the black cable or the supplied 9-to-25 CON-MODEM-adapter. > the light-blue cable is to connect to a PC-AT Serial Port. > > Or crimp an RJ45 Plug reverse on the router's end of the cable . > > Or use a NULLmodemcable beetween Modem and DB9 "con" . > > You should be able to telnet ip-of-your-router 2001 , > authenticate at router, and then speak with the modem. > > If you connect PC with Hyperterm instead of the modem, > and this works, then it will not work with the modem, > and you need to get/build a fitting cable, see above. > > > [...] > > i read when the connection is correct, modem hardware stats should be CTS > > not noCTS. moreover i can not do reverse telnet to modem. > > YOur cabling is wrong, both sides SEND and RECIVE Lines are connected > together > (RS232 i must be shorit-ciruit proof, +-12 V...) > > > > please let me know how i should fix it and configure my modem by AT > > commands. > > Hope this helps, > > Juergen. > > _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
