Interface Configuration Guide 7705 SAR Interfaces
Edition: 01 3HE 11011 AAAC TQZZA 401
v35
Syntax [no] v35
Context config>port>serial
Description This command enables the context to configure V.35 parameters for a channel. Once one of
the three ports on a connector has been configured for a V.35 channel, the other two ports
on the connector can only be configured for V.35. The no form of this command deletes the
V.35 channel.
Default n/a
x21
Syntax [no] x21
Context config>port>serial
Description This command enables the context to configure X.21 parameters for a channel. When one of
the three ports on a connector has been configured for an X.21 channel, the other two ports
on the connector can only be configured for X.21.
The no form of this command deletes the X.21 channel.
If the port has been enabled for an RS-530 interface through the use of an adapter cable,
X.21 configuration applies to the RS-530 interface. There is no configuration specifically for
RS-530 operation. All X.21 functionality is available on the RS-530 interface, except that only
DCE operation is supported for RS-530. However, because X.21 does not support all the
control leads available for RS-530, only a subset of the RS-530 control leads are supported.
Default n/a
character-length
Syntax character-length {6 | 7 | 8}
Context config>port>serial>rs232
config>port>serial>x21
Description This command configures the number of data bits used to transmit a character. This
command is valid only if device-mode is asynchronous. The value for this command cannot
be 8 if the value for parity is anything other than no parity (that is, anything other than none)
and the value for stop-bits is 2.
Default 8
Parameters 6 — specifies six bits in a character
