- Name:
-
- TRSKER, Minimal implementation of the Kermit protocol for
- the Radio-Shack Model II running under TRSDOS.
-
- Sysopsis:
-
- TRSKER { [S:R],F=filespec,B=baud,P=parity,W=word,C=channel,L=recl }
-
- Description:
-
- This version of the Kermit protocol implements only send and
- receive capabilities using the one-character checksum.
- The parameters are given on the command line, between curly
- braces as is usual under TRSDOS.
-
- S Send a file.
- R Receive a file.
- F=filespec Name of the file to send. TRSKER will scan drives
- in the usual TRSDOS order (0,1,2,3,4...) and abort
- if file cannot be found.
- B=baud Supported baud rates are 300,1200,2400,4800,9600.
- But if no baud rate is specified, TRSKER will assume
- 9600 baud.
- P=parity Supported parity codes are N for none, E for even,
- and O for odd. If no code is specified, TRSKER
- will assume no parity.
- W=word Word length is either 7 or 8. If no word length
- is specified, TRSKER will assume 8 bits per byte.
- C=channel Communication channel is either A or B. If no
- channel is specified, TRSKER will assume A.
- L=lrecl Logical record length can vary between 1 and 256
- bytes per record. This is not used when sending
- a file but rather when receiving. When TRSKER
- opens a file to read it, record length will be set
- by TRSDOS. But when creating a file record length
- must be set by TRSKER, (if only because TRSDOS
- will not permit files over 64K records.). If no
- record length is specify, TRSKER will assume 1.
-
- User does not have to specify any of the communication channel
- parameters (B,P,W,C). In wich case TRSKER will assume the
- channel was already initialized by a TRSDOS command (namely SETCOM)
- and will use current settings.
-
- Bugs:
- Command parsing and recovery is minimal.
- During a file transfer, TRSKER remains silent. Only the noisy
- disk accesses of the equipment will tell you that a transfer is
- in progress. (But completion status is unambiguous...)
- TRSKER uses the TRSDOS clock interrupt services to timout
- an unanswered packet but it does'nt seem to work all the time...
