serial ports not seen
Posts: 38
being a pro-mepis newbie has definitely been a better experience than at the major distro players whose interests lie with larger and more profitable fish.
I've downloaded promepis and installed it on my hard drive with relative good fortune and ease. I have however encountered several problems which I'm hoping to resolve as my skill sets improve so I'll be able to run my business fulltime on linux.
my epson perfection(?)1670 unsupported scanner was a problem but with xsane I am able to use it though I'm a little baffled by the file structure and how to save documents efficiently so I can either fax or email them as attachments. which brings me to my next difficulty: I am using an external trendware serial modem (cirrus logic) which works fine in XP. however I notice that when I boot up I get an warning message that:/etc/modprobe.config exists but does not include /etc/modprobe.d!. If I attempt to get into that directory even as Su I get a" permission denied" response which surprises me frankly. In addition, tty0 & tty01 when queried show no file nor directory.
My assumption is that my serial ports are not being seen for some reason. Of course, I really haven't a clue and would appreciate any and all help in this regard.

Dear bob:
this is what I get:
root@1[mikey]# ls-l/dev/ttyS0
bash: ls-l/dev/ttyS0: No such file or directory
root@1[mikey]# ls-l/dev/ttyS1
bash: ls-l/dev/ttyS1: No such file or directory
I can see this printed out everytime I boot up with the modem on and connected. I assume it loads it from memory without the ablilty to re-see it. From windows, I know that this modem is on com1 which is ttyS0. I think something can be done from the setserial command but I'm too much of a newbie to get it resolved that way.

Dear bob:
this is what I get:
root@1[mikey]# ls-l/dev/ttyS0
bash: ls-l/dev/ttyS0: No such file or directory
root@1[mikey]# ls-l/dev/ttyS1
bash: ls-l/dev/ttyS1: No such file or directory
Note the command "ls" "space" "-l" "space" "/dev/ttyS0"
Change to the /dev directory:
# cd /dev
list serial devices:
# ls ttyS*
If you really are missing the devices you can create them with
mknode device_type major_number minor_number
As root change to the /dev directory:
# cd /dev
Create the serial devices:
# mknod ttyS0 c 4 64
# mknod ttyS1 c 4 65
External modems usually don't need anything special.
When you run pppconfig it should be detected and setup automatically
# pppconfig

Dear Bob: thanks for the info. in the interim, I have reinstalled promepis and this time remembered to remove a winmodem from a pci slot. now the external serial fax modem was picked up on the install and its alive. I'm still not there on how to actually fax a doc. maybe you could help me out there. I've downloaded all the packages but none of them work. efax seems to get the farthest but no cigar. One thing I'm sure of is that its easier to do if the modem is working!

What do you get when you list the devices:
# ls -l /dev/ttyS0
# ls -l /dev/ttyS1
Most external modems work fine without any setup and without any special device drivers.
