41 | * Read a variable length non-terminated string (caller specified maximum size). | |
42 | * | |
43 | * @param[in] serial The serial port to read from. | |
44 | * @param[in] count The maximum amount of data to read. | |
45 | * @param[out] buf The buffer to read data into. Must be larger than @a count. | |
46 | * | |
47 | * @return The amount of received data, or negative in case of error. | |
48 | * See @ref SR_ERR and other error codes. | |
49 | * | |
50 | * @internal | |
51 | * | |
52 | * The protocol has no concept of request/response termination. The only | |
53 | * terminating conditions are either the caller's expected maxmimum byte | |
54 | * count, or a period of time without receive data. It's essential to | |
55 | * accept a longer initial period of time before the first receive data | |
56 | * is seen. The supported devices can be very slow to respond. | |
57 | * | |
58 | * The protocol is text based. That's why the 'count' parameter specifies | |
59 | * the expected number of text characters, and does not include the NUL | |
60 | * termination which is not part of the wire protocol but gets added by | |
61 | * the receive routine. The caller provided buffer is expected to have | |
62 | * enough space for the text data and the NUL termination. | |
63 | * | |
64 | * Implementation detail: It's assumed that once receive data was seen, | |
65 | * remaining response data will follow at wire speed. No further delays | |
66 | * are expected beyond bitrate expectations. All normal commands in the | |
67 | * acquisition phase are of fixed length which is known to the caller. | |
68 | * Identification during device scan needs to deal with variable length | |
69 | * data. Quick termination after reception is important there, as is the | |
70 | * larger initial timeout period before receive data is seen. | |

96 | * response would occupy. | |
97 | * | |
98 | * After initial receive data was seen, a shorter timeout is | |
