Multi-Tech Systems ISIHP-4U, ISIHP-4SD manual Reset to Stored Profile Values none Default none

Terminal Adapter AT Commands & S-Registers

X5 Enables printing Calling Line Identification (CLI) at the end of the CONNECT message line. This command does not affect X0, X1, nor X2.

ZReset to Stored Profile Values: none Default: none

Resets TA to its current power-up profile and clears the command buffer. The result is the same as turning the TA off and on. When you type ATZ, the state of the &W command determines where default values originate. &W0 defaults come from the customized configuration in NVRAM, and &W1 defaults come from the factory default configuration in ROM.

Because Z clears the command buffer, it must be the last command in a command string; normally it is issued by itself: ATZ. Note that whereas the &F0 reset command always restores the factory default profile, the Z reset command restores either the factory default or the stored profile, depending on how the &W command is set.

&Cn DCD Control Values: n = 0, 1, or 2 Default: &C1 (DCD normal)

Controls behavior of the DCD (Data Carrier Detect) signal. Normally, the DCD goes high when the TA establishes a connection and drops when the connection is lost. However, you can force DCD to remain high at all times or to remain high except for a brief drop following a disconnect.

&C0 DCD is forced high at all times.

&C1 DCD goes from low to high when TA establishes a connection (DCD normal).

&C2 DCD drops briefly following a disconnect, then rises again. Register S10 defines how long the DCD signal remains low after a disconnect.

&Dn DTR Control Values: n = 0, 1, 2, or 3

Default: &D1 (Exits Data Mode and reenters AT command mode)
