APPENDIX A: SPECIFICATIONS AND SERVICE
The Intele–Modem is a converting modem which works in both Baudot and ASCII codes. It
uses either the industry-standard Hayes or AT command set with extensions to support
TTYs or Intele–Menu commands, an alternate menu-driven command set which can be
used with dumb terminals. The modem features automatic detection of both Baudot and
ASCII calls. It works with commercially available communications and bulletin board
software. Front panel lights indicate current operating mode and line status. Screen
messages signal call progress (dial tone, busy, ringing).
