MODOUT

statement

II
string
ll
t'10DOUT D$
Sends the string to the modem transmit buffer. If the string contains just data, the data is transmitted
out the phone line.
If the string includes low-level modem commands, those commands are not
transmitted, but are processed locally by the modem.
t'10DOUT
also reads the modem receive buffer and
saves its contents in the HP-75 to prevent the possibility of overflowing the buffer from echoed data or
commands (see "MODOUT and Echoed Data" and "MODOUT and Out of Memory" in Section 2) .
• t'10DOUT
waits until the transmit buffer is ready to accept data before sending anything to the
modem. If the modem is deadlocked,
t'10DOUT
will wait forever.
(see "Modem Deadlock" in
Section 2). Once
t'10DOUT
starts to wait, you can halt it by pressing [ATTN] (a low battery
condition in the HP-75 will halt it as well). Then
t'10DEt'1
OFF,
turning the HP-75 off, or

will clear the deadlocked condition.
If you expect a deadlock, you can use
PEAD'y'?
to identify that condition before
t'10DOUT
begins
to wait forever. If deadlock is of great concern, your program should only send one character at a
time to the modem with
t'10DOUT,
waiting before each character is sent until

PARITY?

function

PAfUT\'?
Checks for a parity error. Returns a 0 if the last
t'10D I t·U
had no parity error, or a 1 if there was a
parity error. Remember that
t'10D I

returns not only the contents of the modem receive buffer, but
also any data echoed by
t'1ODOUT. PAF.: I T\'?
reports a parity error for data returned by
