[RESOLVED] COMM-DRV handshing protocol

[makdu]

Hi,
What are the possible handshaking protocol available using COMM-DRV for communication through MODEM

[DataMiser]

Handshaking typically refers to XON/XOFF or CTS/RTS both of which basically just tell the computers when the buffers are full and/or ready to receive data.

A protocol is used for transfering data, typically XModem, Ymodem, ZModem.

I have never heard of COMM-DRV so I have no idea what it may support. I would do a search on the net for info on that control if I were you.

sorry for a silly question.
Is handshaking is same as file transfer protocol :(

[DataMiser]

No, not really. Handshaking is more of a traffic cop where as a file transfer protocol is more of a validator.

Handshaking consists of None, Software [Xon/Xoff] and Hardware [RTS/CTS] or both Hardware and Software.

File Tranfer Protocols could be said to do handshaking as well but it is more along the lines of
checking that the data received is actually the data that was sent and issuing a retry when needed.

Normally in Modem, we go with software Handshaking or none??
I have a problem with the line. Some time it is not getting connected between two computers when dialed. In the code, i dont have any handshaking between the computer. Will having handshaking will reslove the issue and what type of handshaking will be good( hardware/software/none)

[DataMiser]

Hardware is the way to go when available.

I do not think it will solve your intermittent connection issue though.
