null modem test
Is there any software in Debian to test a null modem? What I want is software to run on both ends that will exercise all control lines (DTR, DSR, RTS, and CTS) and display the values of these lines so I can see if my cable is good. If there is no software in Debian to do this then is there some software on the net under a suitable license for packaging? Failing that I'll have to write it myself. :( -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page

Re: Modem Test?
Unless you mispoke, I believe you may be misusing /dev/modem. /deb/modem is not a device itself, only a sym link (the wisdom of which is frequently disputed) which points to the serial device your modem is connected to. You want /dev/modem to be a sim link pointing to /deb/ttyS0. As people have pointed out, you want /dev/ttyS0, not tty0. Hope this helps. Hi I've been trying to connect through my schools dial up system for sometime now with no luck. I'm starting to think that my modem is not configured correctly. I think that my modem is on /dev/tty0. I deleted the device /dev/modem that present initially and made a new symbolic from /dev/tty0 to /dev/modem. Is there any diagnostic test I can run to see if /dev/tty0 is indeed the correct device driver?

Re: Modem Test?
Have you tried something like minicom. It just dials your modem but is nice for doing some diagnostics. You can tell it to use either /dev/tty?? or /dev/modem. You could also tell your ppp dialer to use a tty instead of modem. /dev/modem is just a convenience -- not a requirement. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

I believe /dev/tty0 would be one of your consoles, which you don't want. (unless I'm mistaken) Cheers, - Jim pgpX347QLwbfn.pgp Description: PGP signature
Re: Modem Test?
Hi, For the starters you could try /dev/ttyS0 instead of /dev/tty0. If /dev/ttyS0 doesn't work try ttyS1-ttyS3. The /dev/ttyS0 through /dev/ttyS3 are the com devices in Linux. For testing you could try minicom (comm/minicom_1.75-2.deb in stable) and issue some AT commands (ATI4 might output some info about the modem) to see if the modem responds. I hope this helps.
