9600

From: JEVESTAL To: ALL

I just recently got a 14.4 Fax modem, a Best Data Smart One 1442FX. Does
anybody here have one too?

My CoCo 3 is an unmodified 6809 machine, I do not have a 6309 installed
yet. I am usisng SACIA (Randy’s high speed patches installed) with /t2
xmoded to par=12 and xtp=88. I use CoNect single RS-232 port (compat.
with Tandy rs-232 pak). The is in slot one of my mpi (upgraded for CoCo 3).
I am using ed. 9 clock for the BB XT-RTC. My modem is set as follows:
Compression off and RTS/CTS hardware flow control (AT&K3%C0%M0&D2X4).

I can’t get reliable 9600 baud access at all. Calling Delphi on
the 9600 Tymnet node yeilds dropped characters (average 1 or 2 per
screen), I get the same results from local boards. I use
Supercomm At 9600, Zmodem times out and Ymodem yeilds less than 450 CPS.
This is on both Delphi and local boards. At 4800 baud the modem seems
reliable if I do not do any multi-tasking (at 2400 I can multitask
any program and still download without errors).

Any sugestions on how I can get more reliable 9600 baud? Please
do not respond “Get a 6309 with NitroOS9 (or Powerboost). I plan
to do that one of the days but can’t afford it now.

Thanks,

Jim

    You first step is to verify that hardware handshakeing is taking place. Get
    a RS-232 line status indicator. If you don’t see the RTS lite going off
    and on along with the RD light, then something is wrong with your modem
    setup, or the RS-232 port/setup.

    Just letting you know that I have the same modem though it is hooked to
    my MM1. I have not yet achieved any 9600 baud delphi connections but havent
    tried real hard yet. Initially I was getting 9600 CONNECT on my screen,
    then garbage echoing, and then nada. I will be piddling with this over
    the next month so lets exchange notes, huh?

    Have you been able to call out to local PC boards at 9600 or 14.4?

    Unless the port is real bad there is no reason a 68K based system
    can’t do high speed connects. What is your modem settings? Do a
    AT&V to list them to your terminal. From I hear both S-term and
    TasCom (OSterm) should work fine.
