Hello,
I need to implement a layer to manage the RTS/CTS signals for RS232 communciation using an infineon XE166.
This layer is used to manage the communication with a GSM modem.
The problem is that the Flow control specification is not very clear.
so i have some questions to ask:
In DTE-DCE communication, why DCE is always allowed to send data to the DTE, whereas the DTE should Raise RTS and wait CTS before sending DATA to the DCE.
The other question is, when DTE is sending data to the DCE and in the middle of the transmission process the modem clear the CTS, transmission should be continued or not ??
If anywone can answer me i'll be thankfull.
