Q3800015: I want to send a sequence of non-displayable data to the comport. How can I do this?
Use the WriteByte function. It sends one byte of data to the comport. Usually, you call 'WriteString "ATZ"' to initialize a modem. You can also use the following commands to accomplish this: obj.WriteByte 97 obj.WriteByte 116 obj.WriteByte 122 obj.WriteByte 13 ' 13 means: vbCr, the carriage character

Q3800020: In the documentation it says that it supports simultaneous writes to multiple com ports, but I cannot find this in any example?
Basically this is how it works (illustrated by a VBScript sample): Set o1 = CreateObject( "AxSerial.Comport" ) Set o2 = CreateObject( "AxSerial.Comport" ) o1.Device = "COM1" o1.DeviceSpeed = 19200 o1.Open o2.Device = "COM2" o2.DeviceSpeed = 19200 o2.Open
