RS-232 / Serial Port / Com Port Issues

Hi there I'm currently having issues with my communication with a rs-232/serial device i have. it works. but it causes other rs-232/serial devices to stop communicating properly. i need a way to get the data from this device without using [login to view URL] or System.Threading.Thread.Sleep. when i don't use them i have no issues. but i having trouble getting the data when using readexisting for the comport. i have tried [login to view URL] but with no success. Here is the current code i use on my device data receive. The devices send data every 1 second (i found roughly 960ms) and it uses a none standard data each line composes of <new line>Value<tab>Value. i have Documentation if needed. private void portVictronBMV_DataReceived(object sender, [login to view URL] e) { try { if (![login to view URL]) return; string response = [login to view URL](); [login to view URL](960); if ([login to view URL]("\r\nPID") & [login to view URL]("Chec")) { string vstring2 = ""; string vstring = response; vstring = [login to view URL]("\r\n", "@"); vstring = [login to view URL](0,1); int stringlengh = [login to view URL]; int indexOfSteam = [login to view URL]("@Chec"); int removechar = stringlengh - indexOfSteam; if (indexOfSteam >= 0) vstring2 = [login to view URL](indexOfSteam, removechar); vstring2 = vstring2 + "@CTime\t" + [login to view URL]("h:mm:ss tt"); [login to view URL](() => ProcessDataVictronBMV(vstring2)); //[login to view URL](vstring); } } catch //(Exception exception1) { //LogMessageToFile("IPS", "Recieve Data - " + [login to view URL]); } }
