Siemens 7ML19985AB01 instruction manual Establishing Communication, Connect, 111

Considerations

-set the ’cold start’ (F12) default baud to 1200 by removing jumper J1 on board A.

-set both modems and the OCM-3 baud rates to 1200.

-set the remote modem to operate in the ’answer back’ mode. Refer to modem’s user manual.

Communication

-select serial programming link with OCM-3, from the utilities menu. See Milltronics Utilities Software Disk.

The computer screen will display the letters ’v’. These would normally have gone to the OCM-3 to ask it to send its display, but the modem will have returned it to the screen instead.

Establishing Communication

- type the following:

ATD and the telephone number of the remote modem, then press ‘ENTER’.

The modem will dial the number you have entered. When the local modem establishes contact with the remote modem, the local modem sends a message to the screen (typical).

CONNECT

- press the ‘v’ and ‘ENTER’ keys to turn on the OCM-3’s display-to-serial channel.

The OCM-3 is now on line and communication can be carried out. The user may escape to the main menu of the Utilities software and select another program if so desired.

To close the communication, return to the Terminal Emulation program.
