Subject: Can linux handle > 28.8 modems?
Organization: University of Delaware
I am having problems receiving files with my USR Courier
V.Everything. Using zmodem I get CRC errors and Data subpacket too
long errors. Using ftp or ncftp's get, the file will start out at
3.5KBps and freeze for a few seconds and then pick up again, reducing
the ending rate at 1.3KBps for a 1MB file (I have tried different
files). I used to have a Intel 14.4 modem that worked fine. I am
connecting to the same type of modem (USRC V.*). But putting 1 MB
files with ftp and ncftp goes at the normal 3.5KBps. Also everything
works under win95 (zmodem, getting and putting).
I have tried some of the AT commands, but with no success. I
called US Robotics and they told me that it might be the size of the
receive buffer linux is using. I think they might be right because
when I get the first error it is usually around 40K and that's when I
hear my hard drive spin and the light goes on. Then it will go a
little further and do the same thing. Any help or ideas would be
greatly appreciated, because I use linux a lot more than win95 and I
don't want to have to switch. :)
I am using slackware 3.0 and linux 1.3.70 (I have tried others).
