Reset


Before issuing other commands to the modem, issue a Zn - Perform Soft Reset or &F - Load Factory Default Profile command before the identification or setup process. No specific response is anticipated. The modem may be set up to return numeric, or no result codes. If a reset is used, the following should be considered:

1. Even if a recognizable result is received within 2.6 seconds, the program should continue. (Some modems have a lengthy reset process before responding with a result code; others may be in Q1 or V0 mode.)

2. Following an OK result, an additional 600 ms delay should be imposed. Some modems respond with an OK then do lengthy reset processing, then they are unable to accept additional commands.

After the modem is reset, the first setup string (e.g., verbose rather than numeric result codes) should be issued, then the identification command.
