# See PRM for details of Serial devices

but see blockdrivers below also PRM Archimedes - Chapter "Character Input" pp 137-142 fundamentals pp 174-181 RS432 port PRM RISC OS 3 softcopy Volume 2:Chapter 2:DeviceFS Volume 2:Chapter 2:Serial device PRM RISC OS 3 Volume 5 pp 5-121:122 Parallel and serial device drivers pp 5129:131 updates SWIs OS_ReadSysInfo, OS_SerialOp, OSByte

# OS_SerialOp (SWI &57)

Like OS_Byte, a single call with many operations within it. The operation required, or reason code, is passed in R0. It can have the following meanings: R0 Meaning Page 0 Read/write serial states OS_SerialOp 0 1 Read/write data format OS_SerialOp 1 2 Send break OS_SerialOp 2 3 Send byte OS_SerialOp 3 4 Get byte OS_SerialOp 4 5 Read/write receive baud rate OS_SerialOp 5 6 Read/write transmit baud rate OS_SerialOp 6 7 For system use only OS_SerialOp 7 8 Read/write serial input buffer threshold value OS_SerialOp 8 For a detailed explanation of each reason code, see the relevant page.

# Which is the first serial port on an Iyonix? Top or bottom?

bottom, marked serial 1 - uses both original serial port interface methods and DeviceFS interface methods top is marked serial 2, and uses DeviceFS interface only

# !Serial - Paul Reuvers

Run !Serial - two windows open and icon appears on bar. Win - "Drivers installed.." shows Internal32 2.15 Win - "Active serial ports" is blank, probably because you need to initialise the port. Help file for serial does not work properly with NetSurf.

# BlockDrivers Hugo Fiennes, Rev 12, 11th June 1996

To provide a standard way for applications to access serial devices. Application supporting block drivers can be used with many serial devices, with no modification required to the application code - and it's easier to use than the serial SWIs anyway!

# Programming

There are example progs in PROGRAMZ in SERIAL in c and Basic

# Virus stuff - virus false alarm

The file !Run is stopped from running because the virus checker thinks it has a virus. the message is:- Message from Vprotect --------------------- Warning ...!Run may be infected with the Valid virus. Use Killer ... The file has not got a virus - any obey file named !run containing the line Filer_Run .SOURCE.!Apps will give the error.
