Hi All,

Just my 2 cents ...

I started using Marc's driver with 
hcflinmodem-0.93mbsibeta02060200-1.src.rpm.  I have tried several times to 
use a newer version, but I get periodic hangups.  When I go back to 
0.93mbsibeta, the problem goes away.  We're talking several redials per day 
(some within 5-10 minutes from machine reboot) to being able to stay 
connected for 24 hours with the old driver.  The 24 hour limit is my ISP's 
limit (earthlink).

I am using RedHat 7.3 and I have experienced this phenomenon with kernels 
2.4.18-3, 2.4.18-10, and 2.4.18-18.7.x (latest from rhn).  My internal modem 
is Rockwell International HCF 56k Data/Fax, vendor_id = 127A, device_id = 
1003, sub_vendor_id = 0E11, sub_device_id = B0BC.  I'm using wvdial as my 
PPP dialer.

I know some of you have had similar problems, so add my name to the list.  
I'm wondering if any of you have had any success with older versions like I 
have.

The last version I tried was hcfpcimodem-0.98mbsibeta02110301-1.src.rpm. 
And, yes, I followed the instructions and uninstalled by doing an rpm -e 
hcflinmodem before installing the hcfpcimodem.

I've been using source rpm's to eliminate any other possible problems, 
especially the "RedHat's GCC 2.96 versus the rest of the world problem".

Your thoughts, please.

Sincerely,

Hi Jon, I too experience the occasional hangup. Quite infrequently with the 
latest driver (0.98mbsibeta02110301-1.i586.rpm), which I compiled from 
source. I have had this occur with kernel 2.4.18-6 & 2.4.18-8.1 in Mdk 8.2 
and now kernel 2.4.19-16 in Mdk 9.0.
I have had the hangups occur less often as the drivers were refined through 
the various versions ( I began with the 0.92). I wasn't compiling the 
earlier versions from source though, and was using the pre-complied rpm, so 
I would have likely had better results compiling. I am new to Linux, and the 
concept of "compiling" anything was at first unfamiliar ( and a little 
frightening? lol).

I find however that I do get better performance and fewer hangups with the 
src rpm as opposed to pre-compiled. I am usually able to stay connected for 
several hours at a time w/o difficulty. The driver is performing quite well 
indeed, and while the occasional hangup is an inconvenience, it is one that 
I am able to live with. I do get hangups once in a while with the same modem 
under WinME, so I'm not sure that the problem isn't, at least in part, due 
to line interference or some other external anomaly.

I am thankful to able to use my "winmodem become linmodem" on my Mdk-Linux 
system. It has saved me money and hassle, and I compliment Marc for his 
excellent work on these drivers. It has been pointed out to me that optimum 
performance can be achieved with a hardware, or "real" modem. Perhaps I will 
get one at some point. But, for the time being, my linmodem does the trick!

These are my observations and experience..........
