Page 6: Basic Requirements For All Local Modems (Modems Calling Into A Remote Site)
ASIC EQUIREMENTS FOR ODEMS ALLING DIP S WITCHES Some modems have DIP Switches that control certain features. The settings for these switches are vital to the proper operation of the modem. Even if the NVRAM is set correctly, the modem will still look to the state of the switches upon power-up and can override any NVRAM settings if not set correctly. -

Page 14: 3Com (U.s. Robotics) Modem Bug
(U.S. R In the process of testing various modems to use with the Vortex, we have discovered a bug that only occurs with 3Com modems. The bug is quite simple: During an Autoscan, the Vortex will send many commands back to the device that requests that information and one piece of that information causes the 3Com modem to change its echo mode from off to on. - Page 15 S41=000 S42=000 LAST DIALED #: F00PRESETL16,MGATE1,*,000000001100000000 ERROR AATTII44 U.S. Robotics 56K FAX EXT Settings...

- Page 16 Here's the good news. This bug only happens when a PC tries to Autoscan while the 3Com modem is simultaneously connected to another Vortex and the modem is on-hook. If you try to Autoscan while the modem is off-hook, this bug does not occur.

ODEM ROUBLESHOOTING • DTR must be forced on. Most modems have a LED that will show DTR status. some modems have a DIP Switch that must be enabled or disabled in order to force DTR on. • Make sure that RTS Stands for Request to Send. A way for the computer or control system to indicate to the EF Device that it si ready to accept data. -
