Applicable Modems
Any Hayes compatible modem can be used. Modems with a communications rate of 9600 bps or more between modems
are recommended. Use modems of the same make and model at both ends of the communication line.
Special Internal Relays for Modem Mode
Special internal relays M8050-M8077 are allocated to the modem mode. M8050-M8056 are used to send an AT command
or disconnect the telephone line. M8060-M8066 and M8070-M8076 turn on to indicate the results of the command.
M8057, M8067, and M8077 are used to indicate the status of the modem mode.
All completion and failure internal relays are turned off when another start internal relay is turned on.
Start and Result Internal Relays
When one of start internal relays M8050-M8056 is turned on, a corresponding command is executed once. To repeat the
command, reset the start internal relay and turn the internal relay on again.
Completion or failure of a command is determined as described below:
Completion:
The command is transmitted repeatedly as many as the retr y cycles specified in data register D8109.
When the command is completed successfully, the completion IR is turned on and the command is not
executed for the remaining cycles.
Failure:
The command is transmitted repeatedly but failed in all trials as many as the retr y cycles specified in
data register D8109.
Status Internal Relays
Note:
While M8077 (line connection) is off, the
MicroSmart
cannot send and receive maintenance communication and user
communication through por t 2. When M8077 is turned on, maintenance communication or user communication is enabled
depending on the value stored in data register D8103 (on-line mode protocol selection).
