IIRC there is some setting someplace to control the output, but it is has been YEARS since we set it up. Ours outputs to fixed length ASCII lines, like this:
S 021 00 DN0207 T028000 04/19 10:49 18005551212
E 022 00 T028000 DN0276 04/19 10:56
N 023 00 DN0297 T057000 04/19 10:57 00:00:56 6420092
N 024 00 T050152 DN0207 04/19 11:03 00:00:55
N 025 00 T049157 DN0212 04/19 11:03 00:05:24
N 026 00 T049157 DN0212 04/19 11:08 00:00:32
N 027 00 DN0221 T057000 04/19 11:09 00:09:06 12182402857
N 028 00 DN0221 T057000 04/19 11:12 00:00:20 18127222235
N 029 00 T001000 DN0231 04/19 11:12 00:00:14
N 030 00 T001000 DN0231 04/19 11:25 00:00:03
N 031 00 T049148 DN0203 04/19 11:33 00:00:08
Where S is start record, E and end record, and N a new (or complete) call.
