MSComm Communication Slow

MSComm Communication Slow

MSComm Communication Slow

I,m communicating with an external device via Comm1 using VB6. When I request information from the device, it returns it slowly (~5sec). When I use Hyperterminal to send the same command the response is instantaneous. The port settings and handshaking are set correctly at 57600,n,8,1 and Xon/Xoff respectively. I am using the MScomm1.input command to recieve the info from the device. Addtionaly, I compiled the program to see if it would run faster as an .exe.

Does anyone know why the communication link is so slow when I'm using VB?

We weren't happy with the MSComm control either. Buy a copy of the SAX Comm control, it's much better.

Be warned: There's a lot to it, and some knowledge of the details of serial communications is required.
