BSC Detailed Command and
Response Formats
This appendix is intended as an aid to programmers writing an application program
under one of the following conditions:
1. If you are writing to Protogate’s data link interface (DLI) using Raw operation,
also refer to the Freeway Data Link Interface Reference Guide. If you are using the
embedded DLITE interface, also refer to the user’s guide for your particular ICP
and operating system; for example, the ICP2432 User’s Guide for Windows NT
(DLITE Interface).
2. If you are writing a non-DLI application using a Protogate driver interface, also
refer to the user’s guide for your particular ICP and operating system; for exam-
ple, the ICP2432 User’s Guide for Windows NT (DLITE Interface).
3. If you are writing a non-DLI application using a socket interface, also refer to the
Freeway Client-Server Interface Control Document.
