- I run a two node PCBoard 12.1 system on a Mylex 386 under Desqview
- with a USRobotics HST modem. I open my com port at 19200.
-
- I found that under this configuration, uploads to the board at 19200
- abort.
-
- The way I was able to solve the problem was to take Chuck Foresberg's
- advice in DSZ.DOC:
-
- " Switching to a National 16550A UART chip helps tremendously, allowing
- transfers at 115200 bps instead of 9600 bps with a standard 8250. Arrow
- Electronics 1-800-932-7769 sells National NS16550AN chips mail order
- (credit card) for about $22 each in small quantities."
-
- After getting the new chip, I simply popped out the old 16450 and
- plugged in the 16550A. Nothing to it.
-
- The next thing is to replace PCboard's Ymodem-G
- with DSZ's "Qmodem-G". You MUST be running a registered
- version of DSZ to enable the full flow protocols. Sysops can register
- for free by agreeing to certain terms in the DSZ.DOC.
-
- Change the Ymodem-G entry in PCBPROT.DAT to look like this:
-
-
- G,S,1024,Ymodem-G
-
-
- Then add the following two .BAT files to your \PCB directory:
-
- PCBRG.BAT:
- ----------
-
- echo off
- echo *** Function Keys Disabled During DSZ Operation! ***
- if exist pcberr.fil del pcberr.fil
- set DSZLOG=YMODEMG.LOG
- dsz pB4096 handshake both rx -c -k -g %3
- if errorlevel 1 goto bad
- goto end
- :bad
- copy pcberr.old pcberr.fil
- :end
- echo on
-
-
- PCBSG.BAT:
- ----------
-
- echo off
- echo *** Function Keys Disabled During DSZ Operation! ***
- if exist pcberr.fil del pcberr.fil
- SET DSZLOG=YMODEMG.LOG
- dsz pB4096 handshake both sx -k -g %3
- if errorlevel 1 goto bad
- goto end
- :bad
- copy pcberr.old pcberr.fil
- :end
- echo on
-
-
- The lines that say SET DSZLOG=YMODEMG.LOG will tell DSZ to write
- information on each transfer to a file called YMODEMG.LOG. This way
- you can monitor the Ymodem-G transfers, as external protocols on the
- main board won't write the cps to the CALLER file. Here is what my
- YMODEMG.LOG looks like:
-
-
- S 131072 19200 bps 1140 cps 0 errors 27 1024 D:\PCB\UP\ANSIVIEW.ARC -1
- S 36864 19200 bps 1117 cps 0 errors 7 1024 D:\D1B\EXOTIC.ARC -1
- S 95232 19200 bps 1120 cps 0 errors 18 1024 F:\D4\GUPPIES.ARC -1
- S 56320 19200 bps 1149 cps 0 errors 15 1024 D:\PCB\UP\CHKUP17.ARC -1
- S 15360 19200 bps 1182 cps 0 errors 2 1024 D:\PCB\UP\SOCAL047.ARC -1
- S 20480 19200 bps 1138 cps 0 errors 3 1024 D:\PCB\UP\FRAGS11.ARC -1
- S 52224 19200 bps 1135 cps 0 errors 13 1024 D:\PCB\UP\CARLOG.ARC -1
- S 109568 19200 bps 1130 cps 0 errors 33 1024 D:\PCB\UP\REALTY.ARC -1
-
- cps: ^^^^^^^
-
- DSZ's Qmodem-G is fully compatible with Qmodem's Ymodem-G. The user
- will not be able to tell the diference between DSZ and PCBoard's
- implementation.
-
-
- Good luck!
