-- Hello all! I have a US Robotics Sportster Vi 28.8 which has voice/fax and modem facilities. At the moment I use the supplied QuickLink II software and it's, err...., OK... apart from at least one in three calls being cut off due to some fault.. I also use my modem with lots of comms. software on my Acorn A440 computer with RiscOS 3.1 and SCSIFs 3. I would like an alternative voice /fax modem program for dos/windows and a fax and voice program for the Acorn. If anyone can help, TCITP (the cheque's in the post).. Or maybe someone would be interested in developing one with me.. ** Please respond via email to this post! ** [cross posted to: demon.tech.archimedes and demon.tech.modems] --Mikey __________________________________________________________________ http://www.angel.co.uk/ac/mikey/index.shtml Michael White mike@teapots.demon.co.uk ac@angel.co.uk Aberdeen PGP public Key available on request from above..

I've found QuickLink to be flakey at best - certainly not reliable enough to be left unattended! > I also use my modem with lots of comms. software on my Acorn A440 > computer with RiscOS 3.1 and SCSIFs 3.

Unfortunately, the voice capabilities of the Vi can't be used on a standard (Pre-Risc PC) Acorn. Most voice modems will sample at either 7200Hz or 11000Hz, with 2,3 or 4 bits/sample - 7200Hz@2bits fits nicely into 19200 "baud" - the fastest standard serial speed. USR in their wisdom, at least on my 14K4 Vi, have limited sound sampling to 8000Hz @ 2 bits, which is slightly more than 19200. Perhaps this is something to do with gaining BABT approval? It's certainly possible to write your own software if you have a fast serial port - it's just a case of setting up the modem, and saving the data stream. I found some helpful documentation about the Rockwell chipset - I think from www.rockwell.com. The filename is 288ACCOM.TXT if you want to do an archie search for it.
