Data Buffer for Serial Data Transmission
The i-modul Modem 336 LL 3.0 has send and receive buffers. These buffers prevent the
loss of data, in case the application or the remote terminal can not receive data at this
time. The data buffer can be deactivated together with the error correction (bit direct
mode). When the buffer is activated, the data flow control should be active to avoid a
buffer overflow in the i-modul Modem 336 LL 3.0. If the buffer overflows, the data gets
lost. If the buffer overflows, the data gets lost.
Operation without a buffer and error cor-
rection is only useful for special character framings
.
The function is active as default.
Configuration with AT commands

the buffer in the i-modul Modem 336 LL 3.0
