Error State
This list shows the errors which occured on the port. If
more than five errors have occured since the Com-Server
was last reset or since the last time the error table was
cleared, the oldest entry is always overwritten. The most
recent entry is in first position and the oldest in last po-
sition. Preceding each entry ius the time when the error
occured in hours and minutes since the last time the Com-
Server was reset. You can clear the eror table in order to
have all the entries available again.
No halt on XOFF/RTS/DTR
The connected serial device does not respond to the
stop signal set by the Com Server and continues to
send data. The result may be overwriting of the serial
ring buffer and loss of data. Please check to be sure
the handshake configurations for the devices agree
and the connection cable is properly wired.
Overrun Error
The data register of the serial receiver component was
written even though the previous character could not
be read out. Since this is a purely device-internal event,
this error message is strongly indicative of a Com Ser-
ver hardware error.
Parity Error
A character received on the serial port has an incorrect
or missing parity bit. Please check that the transmissi-
on parameters for the Com Server and the correspon-
ding serial terminal device are the same. Parity errors
can also be caused by use of excessively long cable.
Framing Error
A character received on the serial port does not fit in
the time frame that results from the configured trans-
mission parameters (baud rate, start bit, data bits,
