$RSINIT- 90/X'005A'
Initialize the RS-232-C Interface
When you start the Computer, the RS-232-C interface is initialized to the
following characteristics:
Send/Receive Baud Rate: 300
Word length: 8
Parity: None
Stop-Bits: One
Waitfor completion
of
character
110
Tochange any
of
these, you must call $RSINIT.
Entry Conditions
(16888) = Send/Receive Baud Rate Code:
Most significant four bits = send rate
Least significant four bits = receive rate
See the table
of
baud rate codes in Chapter
8.
(16890) = Wait/Don'tWait Switch
Zero =
"Don't
Wait"
Non-Zero =
"Wait"
