Connect laptop with esi system programmer.
Serial , com port, baud rate 11500.
Laptop does hand shake, password checks comp port and baud rate.
Laptop says online.
When i do button map program co lines, paging, time and date,as a example and save then exit,
that button program on that ext has not changed or the time and date.
I use the same com port and 9 pin on other ksu, vodavi and flash voice mail with no problem. The laptop is a xp.
Thanks Gary S.
