Hi

I was wondering if anyone can help. I am writing a program in vb.net 2008 and need to be able to send and receive files using Zmodem through the a comport. I have search the net and have not found much to do with Zmodem in VB.net. I am already using the System.IO.Ports.SerialPort to send and receive commands through the comport but have no idea how to send or receive a file using the Zmodem protocol.

Does anyone have some sample code that may help me?

Thankyou in advance for any help
