CHAPTER 4 SERIAL PORTS

RPC-150 Page 11

In this mode, you have access to the full 256 bytes.

If you don' t read the buffer and the buffer fills, all

subsequent characters are discarded. INKEY$(n)

may be used anywhere in the program.

3. COM$(n) retrieves all characters in the buffer,

including < cr> 's and other control co des. This

function is commonly used with ON COM$

multitasking statement. You can retrieve 128 of the

256 bytes in the serial buffer at one time.

SERIAL PORT FILE NUMBERS

CAM BASIC references the ser ial I/O ports by file

numbers, similar to DOS. The following table shows

the corresponding file number to serial I/O port and how

they are used with the various ports.

Description File Examples

COM1 1 PRINT "Hello"

PRINT #1," Hello"

INPUT A$

INPUT #1,A$

A$ = INKEY$(1)

COM2 2 PRINT #2," Hello"

INPUT #2,A$

A$ = INKEY$(2)

COM1 is J1, the console port. COM2 is J4, the primary

port.

COMMANDS

The following is a list of CAMBASIC commands used

for serial I/O. Variations for many commands not listed

here. These commands and functions are ex plained in

the CAMBA SIC Programming Manual.

Command Function

CLEAR COM$ Clears serial input buffer

COM$ Returns string from buffer

CONFIG BAUD Sets serial port parameters

CONFIG COM$ Configures port for ON

COM $(n) interrupt

INKEY$ Returns a character from the

serial buffer

INPUT Receives string from port

LIST Outputs program listing

ON COM$ Calls subroutine on serial

input

PRINT Outputs data in various

formats

TAB Tabs to predetermined

positions
