Trouble sending hex data over serial port

Recommended Posts


I can't send non-printable character such as 0x00 over serial port by using MSCOMM32.OCX or NETComm.OCX (NOT .dll!)

How can I do this?

I founded topic with same problem here http://www.autoitscript.com/forum/index.ph...=44920&st=0

somebody has solved problem?

The topic you found you gave has a link to the solution in the last post, which is to the serial port UDF in my signature below.

DalHohm also has a UDF here.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
