Circuit Card Description and Installation
Table 148 lists the synchronous interface specifications and the means of
configuring the interface parameters.
Asynchronous transmission uses an internal clock to generate the appropriate
baud rate for serial controllers.
Table 149 lists asynchronous interface specifications and the means of
configuring interface parameters.
