- The symptoms I see are as follows:
-
- Serial Line
- Rate FAX/data Voicemail
-
- 38K Works great, but Works great
- too slow for 28.8
- with v.42/bis
-
- 57K Will accept AT Doesn't work
- command 1 out of 3
- times and will not
- establish a connection
-
- 115K Works great Flaky as heck
-
- This is over a sample of four modems. All show the above behavior,
- have the 8/8/95 supervisor code, and were all purchased around the
- same time in November.
