5.1 TNC error messages
Listed below are the error messages for data transfer, which are displayed at the TNC. In most
cases the messages are self-explanatory.
General error messages:
BAUD RATE NOT POSSIBLE One interface is configured for 19,200 baud and the other
for 38,400 baud.
INTERFACE ALREADY ASSIGNED Transfer is already taking place via interface, or data transfer
has not been completed.

A to H

E The receiving component has detected an error with one of the following causes:
– Same baud rate not set at TNC and peripheral unit
– Parity bit wrong
– Incorrect data frame (e.g. no stop bit)
– Receiving component of interface faulty
K During the transmission of an error to the TNC the <1> character was not transmitted
after the character.
L An incorrect error number was received after the <1> error sequence (error
numbers 0 to 7 are permitted).
N An expected or acknowledgement was not transmitted within a certain
time.
M For data transmission with BCC, was transmitted three times in sequence.
