SYMPTOMS

When you run the version 3.2 Microsoft Mail Remote for Windows or versions 2.1, 3.0, or 3.2 Microsoft Mail for PC Networks EXTERNAL.EXE program with the Telebit script, sometimes the following display appears when you reset the modem after a successful transmission:

Failure to initialize modem

CAUSE

This problem occurs if the response code stored in the response buffer contains two zeros. The modem was reset correctly; however, the script did not recognize the two zeros as being acceptable--the script was looking for only one zero to be returned.

This error will not be consistent because sometimes the response codes are placed separately into the response buffer. This problem is timing dependent.

RESOLUTION

The lines in the script from the RESET section are:

   clearrsp          ; Clear out any ring signals
   sendln "ATV0"     ; Numeric result codes
   sendln "ATE0"     ; Suppress command local echo
   sendln "ATZ"      ; Reset modem to default settings
   waitrsp 1
                

To resolve this problem, place the waitrsp command after "ATE0", so that the multiple response codes from the different sendln commands do not get included together. The corrected RESET section should look like the following:

   clearrsp          ; Clear out any ring signals
   sendln "ATV0"     ; Numeric result codes
   sendln "ATE0"     ; Suppress command local echo
   waitrsp 1
   sendln "ATZ"      ; Reset modem to default settings
   waitrsp 1
