TTYO TRANSMIT MODEM ERROR STATUS1 : ##, DCD AND/OR CIS
SET
An erro~ has occurred in polled-mode testing of
the t~ansmit modem signals. RTS and DTR were
reset in the receive modem, but nCD and/or CTS
failed to be reset in the transmit modem. Check
the interconnecti~g cable.
TTY# RECEIVE MODEM ERROR STATUS2 : ##, DCD NOT TURNED
BACK ON
Error in polled-mode testing of medem signals.
RTS and DTR were set high in the transmit modem,
but the expected statu3 in the ~ec~i{e modem, CT3
low and DeD high, did not occu~.
TTY# TRANSMIT MODEM ERROR STATUS2 : on, CTS Nor TURNED
BACK ON
Error in polled-mode te3ti~g ~f modem
DTR was set in the receive modem, b~t the
status in the transmit modem, CTS high
low, did not occur.

SIO character received interrupts are used tJ 3i3~

from 00 to FF are transmitted in ~ach direction
for each of the standard line speeds: 19,200,
