| 9 This is done by including the following module in the OS-9 kernel: | |
| 10 </para> | |
| 11 <literallayout> | |
| 12 ACIA51 - Serial Device Driver | |
| 13 </literallayout> | |
| 14 <para> | |
| 15 To load this module into the kernel enter the following command line: | |
| 16 </para> | |
| 17 <literallayout> | |
| 18 LOAD /D0/CMDS/ACIA51 | |

| 22 <title>Serial Printer Implementation</title> | |
| 23 <para> | |
| 24 For those with a serial printer, you can use the serial port | |
| 25 in the redirection of a program's output path by including the | |
| 26 following modifier at the end of a command line: | |
| 27 </para> | |
| 28 <literallayout> | |
| 29 >/P1 | |

| 31 <para> | |
| 32 The baud rate of the serial port may be changed as follows: | |
| 33 </para> | |
| 34 <literallayout> | |
| 35 XMODE /P1 BAUD=3 | |
| 36 </literallayout> | |
| 37 <para> | |
| 38 This will change the baud rate to 1200 characters per second. | |
| 39 For a detailed description of the baud rate see the XMODE | |
| 40 command description. | |

46 For those who wish to connect two &make; computers, running |
| 142 | 47 OS-9, together using the serial port, redirection of the input |
| 48 or output paths is possible using the following modifier at | |
| 49 the end of a command line: | |
| 50 </para> | |
| 51 <literallayout> | |
| 52 >/T1 - for an output path | |
| 53 </literallayout> | |
| 54 <literallayout> | |
| 55 </T1 - for an input path | |
| 56 </literallayout> | |
| 57 <para> | |
| 58 To pass a file of data between the two computers, one must be | |
| 59 configured for input from the serial port and the other | |
| 60 configured for output: | |
| 61 </para> | |
| 62 <literallayout> | |
| 63 Computer 1, BUILD TEXT </T1 - input to port | |
| 64 </literallayout> | |
| 65 <literallayout> | |
| 66 Computer 2, BUILD <TEXT /T1 - output to port | |
| 67 </literallayout> | |
| 68 <para> | |
| 69 Using the above example, the text file on computer 2 will be | |
| 70 transferred to a file called TEXT on computer 1. | |
| 71 </para> | |
| 72 <para> | |
| 73 When the command line is entered on computer 1, the system will | |
| 74 reply with a question mark and wait for information from the | |
| 75 serial port. The command line on computer 2 will send data to | |
| 76 the now waiting computer 1. A string of question marks will now | |
| 77 be seen, this is the number of lines sent and recieved by the | |
| 78 respective computers. | |
| 79 </para> | |
| 80 <para> | |
| 81 To create a log-off sequence after such a transfer, use the DISPLAY | |
| 82 command as follows: | |
| 83 </para> | |
| 84 <literallayout> | |
| 85 Computer 1, BUILD <TEXT /T1 ; DISPLAY 0A 0D >/T1 | |
