This was the latest driver file set for this modem when the Amquest web site shut down. The rss8003.inf driver file (rev.12/98)has a small update from the previous (9/98) version. (added an S9 and S10 command in the initial AT command string) The install program version (220.127.116.11) is unchanged. This zip file is "as downloaded" from the Amquest site. To my knowledge, there was never an actual Win98 version released.
