Witam!

pytanie: 
========
czy mozna zmusic SPARCclassic (Solaris-2.3) do obslugiwania
modemu przy DTE<->DCE > 9600?

opis:
=====
SPARCclassic Solaris-2.3
modem: ZOOM VFX V.32bis Model 350

# eeprom|grep ttya
ttya-rts-dtr-off=false
ttya-ignore-cd=false
ttya-mode=9600,8,n,1,-

fragment /etc/ttydefs:
19200:19200 -parity onlcr:19200 -parity hupcl::19200
9600:9600 -parity onlcr:9600 -parity hupcl::9600

Modem jest:
at&fv0e0x0&c1&d3&s0=1&k0
(odpowiedzi kodami numerowymi, no echo, basic return codes only,
DCD follows remote carrier, on DTR drop soft reset the modem, auto answer,
no controll flow)

Instaluje monitor:
PORT="a"
/usr/sbin/pmadm -a -p zsmon -s tty$PORT -i root \
-v `/usr/sbin/ttyadm -V` -fu -m "`/usr/sbin/ttyadm \
-T vt100 -p "$LOGINMSG" -d /dev/term/$PORT -s /usr/bin/login -l $TTYSPEED -b \
-S n -m ldterm,ttcompat`" -y "dial in/out on serial port"

objawy:
=======
dziala dla TTYSPEED=9600 nie dziala dla TTYSPEED=19200 (nie odpala
/usr/bin/login co widac, wlasciwie nie widac, w /var/saf/zsmon/log)

pytania:
========
1. dlaczego nie dziala?
2. czy moze jakis controll flow wlaczyc? (probowalem hardware ctr flow
  i wtedy mialem:
  19200:19200 -parity opost onlcr:19200 -parity crtscts hupcl::19200
  i nie dzialalo
3. gdzies czytalem, ze SUNy (stare) maja klopoty z > 9600? Prawda/nieprawda?
4. wszelkie sugestie mile widziane

pozdrowienia

Janusz
