| |
| Welcome to RMODEM. The routines below are modem handling code. |
| There is nothing service specific below this point. You will need |
| to set some values in your code such as program name, service title |
| and any additional parms you want to pass to disconnect processing. |
| If a match fails, it usually takes a full 60 seconds for the port |
| to timeout and Rmodem to realize that we've lost carrier or missed |
| a match. If you are using RMODEM to wait for a call, you must turn |
| auto-answer OFF. RMODEM will handle the pickup automatically. |
| |
+-------------------------------------------------------------------------*/
SETUP_RMODEM:
/*-------------------------------------------------------------------------+
| Here we set the communication handler independent values |
| for basic modem support services. It is the responsibility of the |
| application programmer to make sure the following RMODEM values are |
| set and shared by Rmodem and the programmers application. |
| |
| Quiet 0/1 When set suppresses all screen IO. |
| Rmodem_Service Set this variable to a description of the service being |
| connected to. |
| Fatal_Error Reserved variable, indicates success or failure of |
| RMODEM call. Exposed so user can play with it. |
| Scan_Limit Number of characters to scan before aborting. |
| Line_Limit Number of lines to read before aborting. |
| Port Should be set to any valid COM port. |
| Port_Pause On a very fast machine, port pause waits x number of |
| seconds before continuing with a match operation. This |
| gives the modem time to return chars to the port. |
| Command_Pause The amount of seconds RMODEM pauses between sending AT |
| commands to a Hayes Compatible Modem. |
| Modem_Reset The command that sets you modem to it's factory default. |
| Normally, this should be YES,ATZ. |
| Modem_Init Should at least contain YES,ATV1. It's recommended you |
| set your modem up and write the configuration to NVRAM. |
| Modem_MNP Should be 'YES, command string to enable MNP. Turn on |
| extended messages for MNP, set for highest terminal |
| speed (9600) and enable modem speed conversion. Enable |
| auto-reliable and XON/XOFF flow control. |
| Modem_MNP_ACK Return string from modem indicating a reliable connect. |
| Baud Has been tested at 300 to 9600 BPS. If your modem |
| provides speed conversion we recommend using it only |
| with MNP enabled. |
