Hello,
I'm trying to set up minicom to work with a special modem for
communicating with the deaf relay service and with deaf friends and
customers. The modem is in serial port 2. The parameters are 300 baud, 8
data bits, 1 stop bit, no parity, half duplex. The 300 baud speed is
standard for this application, since people are just typing. When I do
minicom -s
as root, I get the message that it cannot find /dev/modem. So how do I
make this file? I am using Redhat 7.1.
Thanks.
John

There are other params you need to change in minicom anyway and changing modem device won't be hard. On Tue, Jan 29, 2002 at 12:44:29PM -0600, John J.

You quoted ttys1, note it should be ttyS0 that's capital S. I just tested minicom on y system as root. The sequence to change the parameters is Ctrl-A z p a q Ctrl-A o (scrol down 2 lines for serial port configuration) where you can make changes. Under A is Serial Device : /dev/ttyS0 (on my system) E - Bps/Par/Bits : 9600 8N1 F - Hardware Flow Control : Yes G - Software Flow Control : No As root you should be able to create minicomrc.dfl. If you want to use minicom program you might need to change the ownership of /dev/ttyS0 to other user or chmod 666 it. If minicom doesn't work you may try program kermit. I used both to connect PC with linux to serial ports on Sun servers. > John > On Tue, 29 Jan 2002, Janina > Sajka wrote: > > > John: > > > > Can you use the source available at: > > > > http://www.zapatatelephony.org/ > > > > On Tue, 29 Jan 2002, John J.

Good, that means your program is running. > However, minicom still won't create the /etc/minicomrc.dfl file. > Incidentally, it has an attrocious interface. Instead of just using a That interface is "block graphics", i.e. there is a frame around the text that pops up on top of the basic text. That's OK for people with good vision but I don't know if you can turn that off or not. > plain text interface it is doing something fancy.

Is your root partition mounter read write? I see no reason for root not to be able to write to /etc or any other partition for that matter. What happens if you try touch /etc/minicomrc.dfl That should create an empty file. Don't know what else could be a problem. > John > On Tue, 29 Jan > 2002, Rafael wrote: > > > On Tue, Jan 29, 2002 at 03:45:28PM -0600, John J.

Yes, minicom uses a text windowing interface library known as ncurses, with line drawing characters around sub windows, and cursor placement escape codes, and the like. For a more basic text interface you might like to try: ftp://mirrors.kernel.org/ibiblio/apps/serialcomm/dialout/xc-4.3.2.tar.gz This is on an ibiblio (formerly metalab) mirror. Short description at: ftp://mirrors.kernel.org/ibiblio/apps/serialcomm/dialout/xc-4.3.2.lsm I don't use the thing much anymore as a terminal program (ppp internet access trumps that easily), but I constantly use the included voice "call" script (highly modified by me), to automatically look up voice phone numbers numbers I have typed into a text file, and dial them for me, then drop the line so I can talk by voice. This is a pure text interface that accepts a search string (key) on the command line. LCR -- L. C.

Boyer ` Rafael @ ` Janina Sajka 1 sibling, 0 replies; 13+ messages in thread From: Janina Sajka @ UTC (permalink / raw) To: blinux-list You have to run minicom -s as root. Are you doing that? Also, you can iteratively work through your serial ports--to be sure you have the right one with 'echo ata >ttyS0' etc on up through whatever -- ttyS3, I suppose. I don't know whether you have any hearing to get benefit from this, but it should sound like a modem answering the phone. Shut it off with 'echo ath >ttyS?' of course. The website I gave you has source, I think, for generating baudot. Don't know how device specific that code is for their board, but I thought it was fairly general when I looked at it some time ago.
