- Summary: Access to com3 unnaceptably slow from dos & win-os2
- Keywords: com port slow com3
-
- Anybody,
- I am having a difficult time getting my dos and windows applications
- to access my com3 at a reasonable speed. The com port is on an internal modem
- and I have the proper interrupt and base I/O addresses defined for com.sys and
- vcom.sys in my config.sys and in the system.ini file for win-os2. I use
- Crosstalk for windows extensively with my 14,4 modem but when it runs under
- win-os2 it takes about 1-2 minutes for characters typed to the modem to
- echo back to the screen. I have tried executing mode.com in the autoexec.bat
- file to ramp the serial port speed up to 19200 and 38400 to no avail. I have
- tried commenting out the vcom.sys line in the config.sys. I have tried using
- dos based terminal programs but have gotten similair speeds. The "PM terminal"
- connects just fine, it doesn't have the function that I need though. This is
- my first installation of OS/2 on an ISA machine; I have installed & used os/2
- on PS/2's extensively, but this problem has me bamboozled. Has anyone had a
- problem sililair to this before? If so, what was the solution?
- I have a 486DX33 on an ISA motherboard with 16megs of memory and about
- 90 megs of free drive space. I am using the 8514/A drivers for a Graphics
- Ultra/Pro (Mach32 chip, not Mach 8) and I have DOS 5 in a primary partion with
- OS/2 in a logical HPFS partition. The mouse seems to function properly on
- com1 in both os2 and dos sessions. The IRQ for com3 is 5 and the base address
- is 03E8. I know that I have crosstalk set up properly because I am running it
- under dos5 and windows 3.1 right now. I haven't tried moving the modem to
- another com port or changing the I/O address but I guess that's my next step
- if no-one has seen the problem before.

- Thanx,
- Stanley Wood
