Operating Modes

Driver mode VScom Driver for Windows NT 4.0, 2000, XP and 2003

Driver Mode creates virtual Com port.

TCP Raw Server Raw data transfer over TCP/IP. Accepts multiple incoming connections.

TCP Raw Client Raw data transfer over TCP/IP. Connects to multiple hosts or devices waiting for incoming connections.

TCP Advanced Settings Special settings for user-defined modes

UDP Mode Raw data transfer by UDP. The NetCom is client and server at the same time. Timeout functionality, maximum packet size and a configurable trigger string define the packets of incoming data to send over UDP

Null Modem Tunnel Connecting two NetCom used as virtual null modem cable.

IP Modem The serial port emulates a standard modem. Operates by AT-commands, and dials to IP-Addresses instead of phone numbers.

Windows "INF"-Driver provided for installation.

Print Server The NetCom accepts print jobs, and spools them to the attached serial printer. Operates as of RFC1197, similar to the line printer daemon in Unix-systems
