INT 14 - X00 FOSSIL(Fido/Opus/Seadog Standard Interface Layer) A standardized API for performing serial I/O, originally used by the Fido and Opus bulletin- board software and Seadog bulletin-board mailer, but now in wider use. - STUFF RECEIVE BUFFER AH = 21h AL = character DX = port number Return: nothing Notes: the given character is inserted at the end of the receive buffer as if it had just arrived from the serial port; all normal receive processing (XON/XOFF, ^C/^K) is performed on the character fully re-entrant SeeAlso: AH=20h"X00"
INT 14 - Alloy MW386 v1.x only - RELEASE PHYSICAL COMMUNICATIONS PORTIBM PC Portable (uses same BIOS as XT) AH = 21h DX = physical port number Return: AX = status 0000h successful FFFFh failed SeeAlso: AH=20h"Alloy",AH=22h"Alloy"
INT 14 - MultiDOS Plus - TRANSMIT CHARACTER AH = 21h AL = character to send DX = port number Return: AH = status (see #00350) Note: monitor mode must have been turned on with AH=24h before calling SeeAlso: AH=20h"MultiDOS",AH=22h"MultiDOS",AH=24h"MultiDOS" (Table 00350) Values for MultiDOS Plus status: 00h successful 39h no DSR or CTS 3Ch no DSR 3Bh no CTS 41h no such port 42h monitor mode not active 97h timed out
INT 14 - PC-MOS/386 v5.01 $serial.sys v5.04 - OUTPUT CHARACTER, WITH TIMEOUT AH = 21h AL = char to send DX = port number SI = timeout in timer ticks (0000h = default) Return: after character is sent or timeout expires Program: PC-MOS/386 v5.01 is a multitasking, multiuser MS-DOS 5.0-compatible operating system by The Software Link, Inc. SeeAlso: AH=01h,AH=0Eh"Digiboard",AH=22h"PC-MOS"
INT 14 - HUNTER 16 - EXTENDED CONTROL AH = 21h AL = command 01h force transmission of buffer 02h clear transmit buffer 03h clear receive buffer DX = port (00h COM1, 01h COM2) Return: AH = extended status Desc: executes the command on the selected port SeeAlso: AH=1Eh"HUNTER",AH=20h"HUNTER",AH=22h"HUNTER",AH=24h"HUNTER"
