How to install it

What to send to the palmtop saves 7.0 KB

These are the files you need. You can send them from the package contents below.

  • COMMCHK.EXE → A:\SOFT programa de DOS 94.0 KB
  • COMMCHK.INI → A:\_DAT configuración 87 B

No need to put COMMCHK.DOC: they are manuals, source code or supporting material. Read them here and save 7.0 KB on a 1 MB disk.

Steps
  1. Copy COMMCHK.EXE to A:\SOFT. They are DOS programs: run them from the DOS icon, or add A:\SOFT to the PATH in C:\AUTOEXEC.BAT to call them by name.
  2. Copy COMMCHK.INI to A:\_DAT, where the 200LX looks for configuration. Open it with Memo and adjust it before use.
  3. If you edit a configuration file on the palmtop, make sure you leave a newline at the end: some programs swallow the last line without saying a word.

Derived from the package contents and the 200LX conventions. It installs to A: on purpose: C: is a RAM disk and every byte there is memory taken from the system.

The author's instructions
setup line as described in Section "A" below.


	Section A:
		The format of the ini file is as follows:


port,base address,interrupt vector		<== serial port setup
port,base address,interrupt vector

-M -B 4800								<== command line parameters.

		The allowable ports are 1 - 6.


	The commchk display is as follows:
PORT1 BUFFER     0.0   SYSTEM BUFFER      0.0   RTS DTR DSR CTS      0     0
		 ^ SIZE OF THE BUFFER FOR PORT 1
					  ^ SIZE OF THE BUFFER USED FOR DISPLAY
				 TOTAL NUMBER OF SERIAL PORT ERRORS  ^
				 LAST RECIEVED SERIAL PORT ERROR CODE      ^

	Commchk keyboard commands are summarized as follows.

		F1 key - Help

		F4 key - Allow changing the serial port characteristics online.

		O  key - Open the currently active capture files

		C  key - Close the currently active capture files

		D  key - Toggle video display on and off

		F  key - Flush out all current serial port buffers
				 of all characters.

		A  key - place the display in ASCII mode

		H  key - place the display in HEX mode

		I  key - Reinitialize the port, also clears all buffers

		Q  key - Quit

		R  key - Toggle the RTS line

		S  key - Shell out to dos - interrups and information flow from
				 one port to the other continues to occur

		T  key - Toggle the DTR line

		L  key - Toggle the line display status line

		M  key - Toggle the Line and Modem status interrupt on/off
				 if you are on a system where the unused lines are allowed to
				 float then they may cause numerous interrupts to occur and
				 appear to lock your system. so turning these interrupts off
				 may fix this problem.

	Commchk Startup defaults are as follows
		2400 Baud, 8 Data bits, 1 Stop bit, No parity
		No capture file, com1 and com2 ports

Send to my palmtop

The palmtop must be waiting before you press the button, or the transfer will fail. It is the palmtop that announces it is ready, not the other way round.
