Library Routine Comments
33 SPoll AllSpoll
SPoll - In Active Controller mode, SPoll performs a Serial
Poll of the specified device and responds with a number
from 0 to 255 representing the decimal equivalent of the
eight-bit device response. If rsv (DIO7, decimal value 64) is
set, then that device is signaling that it requires service. The
meanings of the other bits are device-specific.
Serial Polls are normally performed in response to assertion
of the Service Request (SRQ) bus signal by some bus
device.
SPollList AllSpoll As with SPoll, but uses list.
34 Status ReadStatusByte
Status - returns various items detailing the current state of
Driver488. They are returned in a data structure.
35 Talk
Also see:
MyTalkAddr
ReceiveSetup
Talk - addresses an external device to Talk.
36 Term
NO EQUIVALENT
Term - sets the end-of-line (EOL) terminators for input from,
and output to, I/O adapter devices. These terminators are
sent at the end of output data and expected at the end of
input data, in the manner of CR LF as used with printer data.
During output, Term appends the bus output terminator to
the data before sending it to the I/O adapter device.
Conversely, when Driver488 receives the bus input
terminator, it recognizes the end of a transfer and returns
the data to the calling application. The terminators never
appear in the data transferred to or from the calling
application. The default terminators for both input and
output are set by the startup configuration and are normally
CR LF EOI, which is appropriate for most bus devices.
TermQuery
NO EQUIVALENT
TermQuery - queries the terminators setting. Terminators
are defined by the TermT structure.
TimeOut
NO EQUIVALENT
TimeOut - sets the number of milliseconds that Driver488
waits for a transfer before declaring a timeout error. The
timeout value sets a limit on the total time allowed for an
operation. For example, when using the Enter command all
expected data must be received within the specified timeout
period or a timeout error will occur.
TimeOutQuery
NO EQUIVALENT
TimeOutQuery - queries the timeout setting,
given in milliseconds.
