Serial Port Profiles

CHAP Challenge The interval, in minutes, for which the IOLAN will issue a CHAP re-challenge

Interval to the remote end. During CHAP authentication, an initial CHAP challenge takes place, and is unrelated to CHAP re-challenges. The initial challenge takes place even if re-challenges are disabled. Some PPP client software does not work with CHAP re-challenges, so you might want to leave the parameter disabled in the IOLAN.

Range: 0-255

Default: 0 (zero), meaning CHAP re-challenge is disabled

Enable Roaming A user can enter a telephone number that the IOLAN will use to callback

Callback him/her. This feature is particularly useful for a mobile user. Roaming callback can only work when the User Enable Callback parameter is enabled. Enable Roaming Callback therefore overrides (fixed) User Enable Callback.To use Enable Roaming Callback, the remote end must be a Microsoft Windows OS that supports Microsoft’s Callback Control Protocol (CBCP). The user is allowed 30 seconds to enter a telephone number after which the IOLAN ends the call.

Default: Disabled
