That did not solve my problem. I may not have explained it correctly so I will try again. The script is to send a reminder to me using the at command. If I am online, then it will write to me. If I am offline, then it will email me. If I am online, the script will "interrupt me" with the reminder but it also sends a mail message with the aforementioned, "stty: :Inappropriate ioctl for device". If I am offline, the script mails me two messages. The original reminder and the "stty: :Inappropriate ioctl for device" message.
When I tried the above code suggested by Corona688, I got no message and received a mail message, "Ambiguous output redirect." Therefor I am stuck.

NAME

       ptem - STREAMS Pseudo Terminal Emulation module

SYNOPSIS

       int ioctl(fd, I_PUSH, "ptem");

DESCRIPTION

       ptem is a STREAMS module that, when used in conjunction with a line discipline and pseudo terminal driver, emulates a terminal.

       The ptem module must be pushed (see  I_PUSH, streamio(7I)) onto the slave side of a pseudo terminal STREAM, before the ldterm(7M) module is
       pushed.

       On the write-side, the TCSETA, TCSETAF, TCSETAW, TCGETA, TCSETS, TCSETSW, TCSETSF, TCGETS, TCSBRK,  JWINSIZE,  TIOCGWINSZ,  and	TIOCSWINSZ
       termio  ioctl(2)  messages  are	processed and acknowledged. If remote mode is not in effect, ptem handles the TIOCSTI ioctl by copying the
       argument bytes into an  M_DATA message and passing it back up the read side. Regardless of the remote mode setting, ptem  acknowledges  the
       ioctl  and passes a copy of it downstream for possible further processing. A hang up (that is, stty 0) is converted to a zero length M_DATA
       message and passed downstream. Termio cflags and window row and column information are stored locally one per stream. M_DELAY messages  are
       discarded. All other messages are passed downstream unmodified.

       On  the	read-side  all messages are passed upstream unmodified with the following exceptions. All M_READ and M_DELAY messages are freed in
       both directions. A TCSBRK ioctl is converted to an M_BREAK message and  passed upstream and an acknowledgement is  returned  downstream.  A
       TIOCSIGNAL  ioctl  is  converted  into  an  M_PCSIG  message,  and passed upstream and an acknowledgement is returned downstream. Finally a
       TIOCREMOTE ioctl is converted into an M_CTL message, acknowledged, and passed upstream; the resulting mode is retained for  use	in  subse-
       quent TIOCSTI parsing.
