I think someone mentioned a similar device in the past but I can't
find it in the list archives
> But, Gnokii or Gammu provides support for this type of devices?
for gnokii and gammu it shouldn't make any difference if your
/dev/tty* ports come from 7 distinct USB ports (like in your current
setup) or from a single device/USB port, as long as the operating
system sees distinct and standard serial devices
gnokii has also support for multi-modem devices over Ethernet which
may need scripts to log in and out; those script are similar to PPP
scripts, for an example see Docs/sample/ppp/portech-login
> What is your recomendation?
find a developer's manual or detailed protocol information before
buying, or at least the contents of the CD with drivers
