-V Split Serial Port Speed with Multi-Protocol Auto-Answer
-V0
Enables V.23 split serial port speed connections within the multi-protocol auto-answer
feature.
-V1
Disables V.23 split serial port speed connections within the multi-protocol auto-
answer feature.
Determines whether the serial port uses split transmit and receive speed operation
when using the multi-protocol auto-answer feature. %F0 must also be set.
:V
n CTS Time Delay
Where n is an integer from 0 to 255 representing periods of 12.5 milliseconds. Default
is 0. During MI/MIC operation, sets how long the modem waits before turning on CTS
(Clear to Send).
NOTES
•
The :V command takes effect when :R1 is set. If the CTS signal is already On
before the connection, the :V command is ignored.
•
The modem supports this command in Dial Access Security. :R does not need to
be set.
\V
n Error Correction Result Code Form
\V0
Uses standard long-form result codes: CONNECT <speed>.
\V1
Adds /REL to long-form error correction result codes: CONNECT <speed>/REL.
\V2
Displays long-form error correction protocol result codes: CONNECT <speed>/REL-
MNP or CONNECT <speed>/REL-LAPM or CONNECT <speed>/REL-
CELLULAR.
\V3
Adds /REL to long form error correction result codes: CONNECT <speed>/REL.
Displays Hayes-compatible short-form (numeric) result codes.
\V4
Displays long-form error correction protocol result codes: CONNECT <speed>/REL-
MNP or CONNECT <speed>/REL-LAPM or CONNECT <speed>/REL-
CELLULAR.
Determines whether result codes indicate that a reliable link connection is in effect.
The W setting determines the contents of the <speed> field. Setting -M1 changes the
format of the long-form connect result codes.
Even for a reliable connection, use \V0 when your data communications software does
not expect to see a reliable link result code.
