How ZModem determins timeout?
« on: February 18, 2010, 12:09:32 pm »
Hi!

I have a problem — transmission of long files interrupts with timeout error.  I wonder — how ZModem determines that time out happened, 'cause in log i see that data is being transmitted.

Hello

TnrZModem component has property TimeOut. It is time interval between request and expected reply from remote end.

Sorry I don't understand question.
ZModem protocol is sequence of special request and replies between sender and receiver. If someone do not receive expected reply after its request, we get timeout error. This timeout is ordinary situation in serial communication tasks.

The zeByUnknown signals about error by Timeout and file pointer error during file writing operation.
