How to modify the setting "initString" to change the number of rings for auto answer for a Niagara R2 UNC-520 internal modem
TAC I/A Series
Niagara R2 UNC-520
The Ring to Auto-Answer can't be change.
The UNC-520 is shipped with factory defaults to pick up on the first ring. The internal modem does not answer, a service answers the call. As a result, the "Ring to Auto-Answer" parameter is NON configurable.
