- Here, as promised, is my follow-up on this subject of improving the
- speed of communications under OS/2 2.0.
-
- I received *tons* of responses to this query, so much that I had to
- resort to a cold, unappreciative-looking "form-letter" type thank you
- addressed to all en-masse. Please forgive!
-
- The responses boiled down to several points:
-
- - Install the CSD.
- Hmmm. I'm not sure whether I should do this or not. I had a friend
- take a look via FTP, and he reported that the CSD consists of over 15
- diskettes worth of material! With the next release of OS/2 imminent,
- perhaps it is worth my while to be patient?
-
- - Install a 16550AFN (buffered UART) chip to increase throughput.
- I went out and purchased a 16550AN (notice, no 'F' -- is that a problem?)
- and installed it. To date I have noticed *no* improvement. This may
- (hopefully) be due to requiring a new COMM driver (see below).
-
- - Get an updated COMM driver.
- I am still waiting for the OS/2 version of unzip to arrive via ftpmail,
- then I shall be able to try the newest COMM driver out -- but preliminary
- results do not look promising! I tried a driver called, '16550.SYS'
- and my system reported, 'IRQ is unavailable. Driver was not loaded'
- (or something to this effect). I was trying to use this driver for
- COM1 with an IRQ of 4.
-
- - Use native OS/2 software.
- By far the best solution wherever available, however in my situation
- there is no equivalent OS/2 version of the application I wish to use.
- But I shall keep my eyes open to such a possibility.
-
- - Make sure the following options are set (some require the CSD
- upgrade.
- COM_DIRECT_ACCESS OFF
- COM_HOLD ON
- COM_SELECT port number
- HW_TIMER ON
- DOS_BACKGROUND_EXECUTION ON
- IDLE_SECONDS 60
- IDLE_SENSITIVITY 100
-
- - Turn v.42bis off for UUCICO sessions.
- The majority of UUCICO traffic is compressed news batches, compressed
- uuencoded material, etc. Even though v.42bis is supposed to be smart
- enough to not make transfer times for already-compressed data even
- worse, in the case of UUCP-g it doesn't seem to work very well.
-
- - Add one of the following lines to CONFIG.SYS:
- CALL=C:\OS2\MODE.COM COM1:19200,N,8,1,,TO=OFF,XON=OFF,IDSR=ON,
- ODSR=ON,OCTS=ON,DTR=ON,RTS=HS,BUFFER=AUTO
-
- or
-
- RUN=C:\OS2\MODE.COM COM1:19200,N,8,1,,IDSR=ON,ODSR=ON,OCTS=OFF,
- DTR=ON,RTS=ON,BUFFER=AUTO
-
- I don't know which one is correct, nor why they are slightly different,
- except that in my situation, my system states something to the effect
- of, "Buffer option not supported by this device." -- a problem which,
- I hope, is related to the need for a new COMM driver.
-
- All the above, in a nut-shell, is basically all I have learned. I am
- unfortunately experiencing much the same poor performance problems, but
- I am going to apply the new COMM driver, and wait for the new release of
- OS/2 before I start to get desparate.
-
- Thanks to all who responded!
