Title: linking 2 amigas
Post by: lionstorm on March 20, 2003, 11:33:02 AM

Hi all,
I have a towered A1200 connected to the net with a 56k modem on one side and on the other side a desktop A1200 with a pcmcia modem card. Can I connect the 2 together (I am not asking about sharing an internet connection here) with this material or do I have to use serial/parallele ports ?

you will need to use a null modem cable or lap link parallel cable top libk the two

ok thanks. I think I mixed ethernet and modem here. But since the modem is having a line in and line out, can you not just connect the 2 modems together so that you can communicate between the 2 amigas ?

No. Your options are basically null modem cable, parnet cable, or ethernet.

The modems won't help unless you have two phonelines and don't mind paying for your network by the minute :)

If you just want a simple way of transferring files, try ParNet. I actually set up a non HD 1200 to my towered beast and had a custom startup floppy in there that mounted parnet and assigned all the system stuff to the towered machine. It was kinda neat ;-)

Yes, you can.

Incorrect.  You can connect two modems together without the use of two phone lines.  I have done it, though it was a long time ago.  Simply have one standard phone cable going between them is enough.  Since they're not connected to any phone lines, they will not receive a dial tone.  So, the trick is to tell both modems to ignore the looking for/lack of the dial tone.  That has to be done on both modems, and you'll have to look up the command for it in your manuals (I don't remember what it is) for each one of them.  Once you have them set to ignore the lack of dial tone, you simply issue the command on one of them to answer (AT A) and the other one to originate (AT D or AT O, I believe).  They should sync up and connect to each other without problems.

Well, OK but the unecessary analogue modulation and demodulation would make it slower than a null modem cable, so why bother? :-D
