ok i have got all usb to serial done and soldered the max 233 as the diagram suggests and when i do the hyper terminal and plug the modem in nothing happens,its supposed to show up the options to show the mac adress but nothing happens...what am i doing wrong,the com port in mine is 3 and that is where the usb port is and is working fine,

which leads do i have to leave in?

coax cable?
usb to modem?

either ur wires from ur max233 to the modem is wrong, double check the wires from ur max233 r going to the correct pins on the modem eg: v,gnd, rx tx from ur max232 to the gnd, tx, v, rx on the modem and the soldering is ok and not touch each other and also make ur baud rate is setting is correct if... still no joy, then it might be a problem with ur serial port try com port 1 to see if it makes any difference
 
yes i have checked the solder joints,they are ok,you said of the baud settings i do not know how to do that?

Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

and r u sure ur the wires r connected correctly

yes i have done that,sorry not know what that meant,i have checked all the joints and look ok,what i might do is get another one and start again just to be on the safe side
 
Set your IP address to 192.168.100.10
Set your GateWay to 192.168.100.1

Start tftpd32.exe

Connect your network cable and MAX232 to the NTL250, start hyperterminal (115200 baud, 8 data bits, 1 stop bit, no parity and no handshaking) and power the modem on without the cable feed attached.

Enter '1', '2', or 'p' within 2 seconds or take default...

Press P

hope it helps......
 
where is everyone getting these 200 and 250 modems from??

i'm still on an old 120 modem
 
I got mine from Fleabay for £7.50, cheap and cheerful.
 
what are the advantages of the 250 and are they easy to mod?
 
anyone got 1 spare without using fleabay,not trust that site for those kinda things
