MicroTAP Technical Support


  Lost Records at PostScript Page Breaks:

If your serial number is less than 1628 (or the file date for export.ps is earlier than 10/5/94), download export.ps and replace the old version to fix this problem.


  Intermittent PCMCIA Port Failure at startup in Win95 DOS Box:

When restarting MicroTAP under Windows 95 (running in a DOS box) the PCMCIA port may be unable to receive data. A simple workaround for this problem is to open and close the Port Setup dialog (execute Ctrl+P, Enter) which resets the PCMCIA serial port.


  Changing Character Sets:

The first question most users ask is how to load a different character set. It is simple: Press Alt+F (for the file menu), O (for Open), C (for Character set), Tab (once only to move to the filename box), use the arrow keys to select (highlight) a new character set, Enter (to open the character set and close the dialog).


  PCMCIA Card Installation:

Over half of all technical support inquiries concern PCMCIA card installation. Most PCMCIA card installation problems involve the assignment of the serial port's interrupt level. In general, there are some basic rules to remember:

•  Make sure your PCMCIA card does not conflict with an internal modem (look on the back of your laptop for the telltale RJ-11 port. Many laptops have internal modems that are assigned to the COM2 base address (0x2F8) and IRQ (3). Usually, interrupt 5 is available to assign to the PCMCIA card - if not, you may need to disable the modem.

•  Internal (motherboard) serial ports are not designed to share interrupts. MicroTAP is capable of sharing interrupt levels but only high quality serial expansion cards actually implement interrupt sharing.

•  You can use Socket Services if you are running under Windows 95. In any case, you must have a driver installed (use either Socket Services or install the driver included with your PCMCIA serial card) for MicroTAP to see your PCMCIA port. If you install a driver, don't forget to run the enabler whenever you use the PCMCIA serial port!

Symptoms of PCMCIA card installation conflicts:

•  You can receive characters with COM1 (the motherboard port) but not with the PCMCIA port and this remains true when you switch the DTE/DCE input cables (except that you see characters from the other side of the conversation).

•  You receive the first character of a group on the PCMCIA channel and/or get many serial overruns or other errors only on the PCMCIA channel.

•  You receive modem echo characters on the PCMCIA channel but not much else (except errors).
