This command is used to set the bus timing parameters. The card must be off line to use this command. The units for all timing parameters are in bit-times, the inverse of baud rate.
All network parameters are optional, or will be ignored if specified as '*', permitting only the desired parameters to be modified. If no network parameters are specified, then the command reduces to a query. In all cases, the current values of the parameters are returned.
This command is typically used in the configuration file. However, the card resets all network parameters to their defaults every time the card is taken off line, making it necessary to re-issue the command before returning on line.
The bus timing parameters that are not specified are automatically calculated by the card based on the baud rate. If the baud rate is changed after its initial setting by the first call to pfbNetParms, then the card can no longer detect which bus parameters were unspecified and therefore will not re-calculate them. Putting the card on line, then back off line resets the defaults and permits the bus parameters to be re-calculated correctly.
