SIOMODEM - a test of the SIOs, including modem signals
PARAMETERS
SIOrvlODEM is an inter'active te::;\':'; it re\~eives no parameters
fr-om SADIE.
DESCRIPTION
SIOMODEM tests the following SIO functions:
$ Character transmission, polled mode .
.g Char act er t ran 3m i 3;3 LJ:1, in t err upt mod e (It S tat usa f f ~ c t s

-9 Ch ar act er t ran sm iss ion, i !1 t er l" up t, m ,) de (" s tat, d.3 :3 f ':"'~.~ ::'.3

~ SIO modem signals (RTS,DCD,DTR,CTS), polled mode.
~ SIO modem signals, inter~upt moje.
~ Tra~smit interrupts.
~ External status interrupts.
~ Character transmissions, mismatched baud rates.
~ Character transmission at all standard baud rates.
The tests are arranged in three different test
each of which is performed for each pair of tty
tests are:

(1) Polled mode character/modem t83t. Performs a test of
character transmission and SIO modem signals.
(2) Interrupt mode character test. Performs a test of
character transmission in interrupt mode where "status

rates.
(3) Modem/character interrupt test. Performs a test of
character transmission in interr'upt mode where" status
