- I use a DS3100 with Ultrix 4.2a for dialout and dialin without having ANY
- trouble with DTR or with communications up to 9600. Since July this system
- has logged over 600 hours of modem traffic (MultiTech V.32) and the only
- complaint that I have is the lack of cts style flow control. Have you
- tried setting your modem to hold DTR?
