Making a Call using Vmodem in Normal Mode
Using Vmodem, telephone numbers are replaced by the IP address and TCP port of the Vmodem port you
are calling.
1. To place a call using the device attached to a Vmodem port, the ATD sequence would be:
ATD<IP address><Port>
Where:
IP address is the IP address of the IOLAN unit that you are calling. where each number is
represented by three digits (padded using zeros where necessary) with no separating dots.
Port is the local TCP port of the Vmodem port on the IOLAN unit you are calling,
(By default the TCP port is 10000 plus the number of the serial port using Vmodem.
For example, Port 12 would become 10012).
For example, to connect to a host IOLAN with an IP address of 196.65.144.236 and serial port 4
configured as Vmodem normal mode, the ATD sequence would be;
ATD19606514423610004
2. The Vmodem now returns a numerical or text string to indicate either a successful or failed connection.
You can configure how this indication is displayed see the appropriate section within this note.
Disconnecting a Call in Vmodem Normal Mode
1. To disconnect a call, the sequence +++ATH is sent to the Vmodem port.
(This is not echoed by the port)
