I'm having some strange problems getting a modem to work with FreeBSD. I
originally started by attempting to get ppp up and running- after a
vanilla 2.2.7 install. The modem is a PNP USR 56k modem, which was set to
use com3 by Windows 98. ppp has no trouble recognizing the presence of
the modem on cuaa2, but has a VERY strange behavior when talking to the
device. (I can duplicate all these problems with minicom- I don't think
ppp is the culprit, and everything works perfectly under windows98.)
I tried building a new kernel with
controller pnp0
in the configuration file, but the new kernel could not find any pnp
devices. The computer seems to be recognizing the modem- when running
ppp, I can do a
set device /dev/cuaa2
and talk to the modem, but the modem does not send any characters to the
console unless prompted by the next character in the input from the
console.
In addition, typing basic commands to the modem don't ever return any text
responses. ('OK', 'NO DIALTONE', 'BUSY', etc...)
For instance, I can type to the modem:
"at"
and it displays
a
until I type a "^M" and the cursor returns to the start of the line and
displays
at
In addition, I can type
"atdt1234567"
and the display is always 1 character behind what I just typed.
I type: display:
a
t a
d at
t atd
1 atdt
2 atdt1
3 atdt12
4 atdt123
5 atdt1234
6 atdt12345
7 atdt123456
^M atdt1234567
and the modem correctly dials.
NOW, the really funny behavior comes in. I dial up to my isp, and the
modem appears to sit there idle- until I start typing spaces to the
console. It appears that each space typed to the terminal echoes ~16
characters. I can hit spaces until I get to the login prompt (which has
already gotten n spaces past login:), get past the authentication, switch
back to packet mode (in ppp) and then sadly watch the modem disconnect...
All of this while entering commands w/o spaces - just assuming that the
modem is correctly sending characters to the other end of hte connection.
I tried fiddling with E/F commands to teh modem to no avail... It appears
to be a problem with the modem echoing incorrectly, but I have the feeling
that the kernel is having some problems correctly interfacing with the
vacuous (non pnp configuration of a pnp card) communication to the device.
I took the liberty of printing out all the ati commands
(NOTE: I held the space bar down for a good 1/2 hour to see all the
characters of this output from the modem...)
Any help would be greatly appreciated- I'm stuck.
Thanks,
Josh
