I am trying to communicate with a serial device called a DataLink(DL). This DataLink is a protocol converter and a communication controller. The purpose of my program is to configure the DataLink (ie. Set the DL's COM and IRQ ect). My problem is this: When I transmit a message in ASCII or HEX (ie: DLE STX ETX .... OR IN HEX 10 02 03.. ect) the DataLink will reply with an "ACK" or "NACK" meaning a correct or incorrect transfer configuration. I am capable of transfer to the DL but cannot seem to be able to capture its response into VB. I have set the RThreshold to 1. I would like to be able to trap the message in a text box with the use of: MScomm1.Input
Text1.text = Mscomm1.Input
But this isn't working. Can you help me ? I would appreciate it enormly !
