COMSPHERE 392xPlus Modems
Asyn #Data Bits: 8
Nxt 8 7 9 6
This configuration option only appears when Async/Sync Mode is configured for Async.
Asynchronous Number of Data Bits. Determines if the asynchronous data length is composed of 6, 7, 8, or 9 data bits.
This data length excludes start, parity, and stop bits.
8 – Sets data length to 8 data bits.
7 – Sets data length to 7 data bits.
9 – Sets data length to 9 data bits
6 – Sets data length to 6 data bits.
Asyn #Stop Bits: 1
Nxt 1 2
This configuration option only appears when Async/Sync Mode is configured for Async.
Asynchronous Number of Stop Bits. Selects 1 or 2 bits to signal the end of an asynchronous character.
Async OverSpeed: 1.0 %
End 1.0 % 2.3 %
This configuration option only appears when Async/Sync Mode is configured for Async.
Asynchronous Overspeed. Provides rate compensation for asynchronous DTEs that may be operating at a slightly
higher rate than the asynchronous interface of the port. It accomplishes this by shortening the duration of the stop bit.
1.0 % – Causes the stop bit to be shortened to 87.5% of its original duration.
2.3 % – Causes the stop bit to be shortened to 75% of its original duration.
DTR Action: Ignore
Nxt Ignore Stndrd_RS232 CntrlsOnHook
Data Terminal Ready Action. DTR is a signal from the DTE to the modem indicating that the DTE is connected and
ready for operation.
NOTE: Only the Stndrd_RS232 setting is allowed in Austria.
Ignore – Modem assumes DTR is always ON. This is used when the DTE does not provide DTR.
Standard RS232 – Allows the DTE to control DTR to the modem as specified in EIA-232-D and ITU-T V.24
specifications. If this signal is not present on at least one port, the modem will not answer or dial.
Controls On-Hook – Required for applications in which the host processor must reset itself for the next session before
the current session is terminated. When selected, the modem does not disconnect from the VF line during an active call
until DTR is lowered by all DTE ports. This setting is ignored if the modem is commanded to disconnect from its own
front panel or by the COMSPHERE 6700 Series Network Management System.
