This program was designed as a utility tool to allow the user to send and recieve data from a serial com port while monitory the byte data. If a loopback ciruit is made on the com port(jumper send to recieve DB9 pins 2 & 3) a developer can also monitor the way VB interprets the data that is being sent or recieved. The port settings can be configured as desired and the last setting are stored in the registry under the Key HKEY_LOCAL_MACHINE\Software\ Damage Inc\Com Settings . The Input Mode Property Defaults to binary. It was not designed to poll the com port or use handshaking with a device, it was intended to send data to a device and then read the devices response as a simple tool. The code maybe modified as desired and may be freely redistributed. I hold no responsiblity for the way it is used. It has been tested on Windows NT 4.0 SrvPk 6a and on Windows 2000 SrvPk 2. It was developed under VB6 SrvPk 5.-This program was designed as a utility tool to allow the user to send and recieve data from a serial com port while monitory the byte data.
