| 34 | .Sh SYNOPSIS | |
| 35 | .Cd device isa | |
| 36 | .Cd device rc | |
| 37 | .Sh DESCRIPTION | |
| 38 | The | |
| 39 | .Tn RISCom/8 | |
| 40 | is an eight port | |
| 41 | .Tn ISA | |
| 42 | .Tn RS-232C | |
| 43 | communications multiplexer with a built in | |
| 44 | .Tn RISC | |
| 45 | processor. | |
| 46 | It uses a block of sixteen | |
| 47 | .Tn I/O | |
| 48 | ports in the range 0x200 to 0x3f0 selectable by on-board | |
| 49 | switches or jumpers. | |
| 50 | The block must be aligned on a sixteen port boundary. | |
| 51 | .Pp | |
| 52 | This driver is mostly based on the Cirrus Logic CL-CD180 driver. | |
| 53 | .Sh HARDWARE | |
| 54 | The | |
| 55 | .Nm | |
| 56 | driver provides support for the | |
| 57 | .Tn SDL | |
| 58 | Communications | |
| 59 | .Tn RISCom/8 | |
| 60 | boards. | |
| 61 | .Sh DIAGNOSTICS | |
| 62 | The following driver specific error messages | |
| 63 | may be reported: | |
| 64 | .Bl -diag | |
| 65 | .It "rc%d channel%d: interrupt-level buffer overflow" | |
| 66 | An internal buffer overflow error has occurred on | |
| 67 | the listed channel. | |
| 68 | The | |
| 69 | .Nm | |
| 70 | driver will need to be reloaded to correct this. | |
| 71 | .It "rc%d: Bad char chan %d" | |
| 72 | The channel has obtained a bad set of characters. | |
| 73 | .It "rc%d: Got extra chars chan %d" | |
| 74 | The | |
| 75 | .Nm | |
| 76 | driver got more characters than expected on the channel shown. | |
| 77 | .It "rc%d: data mismatch chan %d ptr %d (%d != %d)" | |
| 78 | Data sent from channel | |
| 79 | .Ar %d | |
| 80 | to the rx buffer was different then expected. | |
| 81 | .It "rc%d: channel %d command timeout, rc.c line: %d" | |
| 82 | A command timeout has occurred on the channel, the | |
| 83 | .Pa src/sys/dev/serial/rc/rc.c | |
| 84 | file can be consulted for more information. | |
