I, too, have a USR 56K Sportster Voice/Fax Internal PnP modem. I am trying
to get mine going with RedHat 5.1. I, too, have read the ppp-howto to no
First, this is NOT a winmodem. However, it is listed in the RedHat list
of incompatible modems. An excerpt from that list:
========== excerpt ==============
Modems that require software drivers for compression, error correction,
PCI Memory Mapped Modems (these do not act like serial ports)
Internal SupraExpress 56k
Internal SupraSonic 56k
Newer Internal Laptop Modems
The Multiwave Innovation CommWave V.34
US Robotics WinModem series
US Robotics Sportster Voice/Fax modem (X2 model 1785 internal
======== end excerpt =======================
So, it seems to be in this list because of the software for compression,
etc. Well, I just can't believe I won't be able to get the thing to work
at all, but I have yet to figure it out. I think the only difference
between it and the Sportster Fax Modem is some software for Voice support,
but I may be wrong.
I also reconfigured the jumpers so the modem is not plug-n-pray,
but rather hardcoded to IRQ5, COM3. This setting works with Win95 and
WinNT. Linux has not been able to recognize the modem at all. I have
tried minicom to talk to it, with no response to the modem commands.
My only other thought is that there is some conflict with my sound card (a
SoundBlaster AWE64), since it also does not work under linux. In the two
Windows environments, it is running under IRQ10. I don't understand why the
soundblaster doesn't work, as it seems to be supported by RedHat 5.1. Using
isapnptool has not worked.
Has anyone had success with this modem specifically? Swamy and I
would love to hear about it.
