Re: [gentoo-user] Null Modem Cables Between Windoze XP and Linux
Minicom is also a program that works OK. Another approach would be to run ppp over the serial line and make the windows log into the Linux dial-in server. (actually its the way ISPs worked with modem users years ago) But if that's not a matter of pure testing I'd say its a waste of time for transfering files. You can make/get yourself a crossover cable and connect the machines through their LAN Cards over Ethernet at speed near 100mbits/s. It's the thing I would do. -- Best regards, Daniel -- gentoo-user@gentoo.org mailing list

If you are looking for a linux client, look for a program called kermit. It's been at least 5 years since I last used it, but I believe that is what we used to use.

For parallel I remember that lantastic-z had a parallel cable and there was some other program under dos which used to use a parallel cable.

So, I found in the depths of some old computer hardware box this old Symantec null modem cable, plugged it between my X40 and XP Desktop, and hoped for the best. I was able to configure XP as the host with no difficulties, however, I'm not sure what to do about Linux. I'm looking though Kuroo for things about Null Modems, but I'd imagine there's a more command-line friendly way to do this, since I am very much pro-command line. ---snip--- The problem you'll face is the protocols on both ends of the wire will have to be the same. That said, you won't have much luck. However, I ran a similar setup between two linux computers using plip... Something like a poor mans ethernet. Good luck -- gentoo-user@gentoo.org mailing list

A nul-modem though used to be serial and as such worked the normal tty stuff. That's right. Null modems are used for serial connections (i.e. to a serial console on your Linux box). Between two machines you would usually use a null modem cable and set up a new modem connection on the OS software side so that they communicate using a common protocol, e.g. tcp/ip. To send files you could use X Y or Zmodem and a comms application. Not entirely sure what a command line approach would be (a getty or anything that works over tcp/ip I guess?)
